Understanding similar to vs similarly to can be confusing because both expressions describe a relationship between things, actions, or situations. However, they have different grammatical functions, and choosing the right one depends on what you want to compare.
Similar to is an adjective phrase used to describe resemblance, while similarly is an adverb that commonly connects related ideas or describes comparable actions. The expression similarly to is also grammatically possible, but it can sound unnatural when the comparison is not clearly expressed.
For students, English learners, researchers, and professional writers, the most important rule is to compare the correct elements of a sentence. For example, when discussing how two scientific samples were obtained’
you should compare the methods used to obtain them, not the method used for one sample with the other sample itself. Understanding this distinction helps you write more clearly, avoid common grammar mistakes, and choose natural expressions such as similar to, similarly, like, and in a similar way to.
Quick Answer: Similar To vs Similarly To
Similar to describes a resemblance between people, things, ideas, or characteristics. For example, “This design is similar to the original.” Similarly means in a comparable way and commonly connects related statements. Similarly to can be grammatically correct when the comparison is clear, but it often sounds awkward. When comparing actions or procedures, use a parallel construction such as “The samples were obtained in a way similar to how the original samples were obtained.”
Why Do People Confuse Similar To and Similarly To?
People confuse similar to and similarly to because both expressions are related to the idea of likeness. The difference becomes clearer when you understand the parts of speech and the structure of the sentence.
Similar is an adjective. It describes a person, object, action, or idea as resembling another. The phrase similar to commonly introduces the person or thing being compared.
Similarly is an adverb. It means in a similar way or to a comparable degree. It can modify an action or connect one statement with another. Although similarly to can introduce a comparison, its meaning and grammatical relationship must be clear from the sentence.
Consider these examples:
- My phone is similar to yours.
- The first company reduced its expenses. Similarly, the second company cut unnecessary costs.
- The two samples were obtained in a similar way.
The first sentence compares two phones. The second connects two related actions. The third compares the methods used to obtain two samples.
The main issue is not simply whether similar is an adjective or similarly is an adverb. You must also consider what is being compared and whether the sentence makes that comparison clear.
What Does Similar To Mean?
Similar to is an adjective phrase that means resembling someone or something in appearance, qualities, characteristics, structure, behavior, or other features.
It commonly follows linking verbs such as be, look, seem, and appear. It can also describe relationships between ideas, results, methods, and objects.
Examples of Similar To
- This painting is similar to the original.
- Your handwriting looks similar to mine.
- Her opinion is similar to my own.
- The new model is similar to the previous version.
- The results were similar to those reported in the earlier study.
- This procedure is similar to the method described in the research paper.
In each sentence, similar to identifies a resemblance between two things or concepts.
For example, in “The results were similar to those reported in the earlier study,” the phrase compares the current results with earlier results. It does not suggest that the two sets of results are necessarily identical.
When Should You Use Similar To?
Use similar to when the main purpose is to describe resemblance.
It works particularly well when comparing:
- People and their characteristics
- Objects and their appearance
- Ideas and opinions
- Research findings and previous results
- Procedures and methods
- Products and their features
Example: The process for obtaining the fragments was similar to the process for obtaining the sticks.
This sentence clearly compares one process with another. Both sides of the comparison refer to procedures, so the meaning is easy to understand.
What Does Similarly To Mean?
Similarly to is an adverbial construction that can express a comparison between actions, methods, or situations. However, it is less common and often less natural than alternatives such as like, similarly, and in a similar way to.
The word similarly means in a similar or comparable way. It can modify a verb or connect related statements, depending on how it is used.
For example:
- The second student performed similarly to the first student.
- Similarly, the second research team reported comparable findings.
- The fragments were obtained in a way similar to how the sticks were obtained.
The first sentence uses similarly to to compare performance. The second uses similarly to connect two related statements. The third explicitly compares the procedures used to obtain the two sets of objects.
Is Similarly To Grammatically Correct?
Yes, similarly to can be grammatically correct. However, grammatical correctness does not automatically make a sentence the clearest or most natural choice.
Consider this sentence:
“The fragments were obtained similarly to the sticks.”
The construction is possible, but it is awkward because the intended comparison is unclear. The fragments are objects, while the sticks are objects too. Yet the writer probably wants to compare the procedures used to obtain them.
A clearer version is:
“The fragments were obtained similarly to how the sticks were obtained.”
An even more explicit version is:
“The process for obtaining the fragments resembled the process for obtaining the sticks.”
Both alternatives make the intended comparison easier to understand.
Key rule: When using similarly to, check whether the reader can easily identify the two things, actions, or methods being compared.
Similar To vs Similarly To: Comparison Table
| Feature | Similar To | Similarly To |
| Main word | Similar | Similarly |
| Part of speech | Adjective | Adverb |
| Main function | Describes resemblance | Expresses a comparison involving a manner, action, or situation |
| Common usage | Very common | Possible but often less natural |
| Typical context | Comparing objects, ideas, results, and methods | Comparing actions or ways something happens |
| Example | The results are similar to the earlier findings. | The second team performed similarly to the first. |
| Common alternative | Comparable to, resembles | Similarly, like, in a similar way |
| Main concern | Make sure the compared things are clear | Make sure the comparison is parallel and natural |
The important distinction is that similar to is a standard adjective phrase, whereas similarly to is an adverbial construction that may require more careful sentence structure.
When to Use Similar To vs Similarly To
Choosing the right expression depends on the relationship you want to describe.
1. Use Similar To for Direct Comparisons
Use similar to when comparing the characteristics of two people, things, or ideas.
Examples:
- This phone is similar to my old phone.
- Her writing style is similar to that of her favorite author.
- The new policy is similar to the previous policy.
- The results are similar to those of the earlier experiment.
This construction is generally the best choice when comparing nouns or noun phrases.
2. Use Similarly to Compare Actions
Use similarly when describing an action that occurs in a comparable way. Add to when the sentence naturally requires a comparison with a person, action, or reference point.
Examples:
- The second team performed similarly to the first team.
- The two samples were processed similarly.
- The new system operates similarly to the older system.
The first and third examples compare performance or operation. The second describes the way the samples were processed without specifying a comparison object.
3. Use Similarly to Connect Two Statements
When the comparison involves two complete statements, similarly often works best as a linking adverb.
Examples:
- The first study found a significant improvement. Similarly, the second study reported positive results.
- The company updated its website. Similarly, it improved its mobile application.
- One student completed the assignment early. Similarly, another student finished before the deadline.
In these examples, similarly connects related information. It does not need to be followed by to.
4. Use In a Similar Way To for Clearer Comparisons
When comparing methods or procedures, in a similar way to can be useful. However, you must still make sure that the comparison is clear.
For example:
Less clear: The fragments were obtained in a way similar to the sticks.
Clearer: The fragments were obtained in a way similar to the way the sticks were obtained.
More concise: The fragments and the sticks were obtained similarly.
The best version depends on the surrounding context. If the methods have already been explained, the concise version may be sufficient. If the reader needs to understand exactly which procedures are being compared, the longer version is clearer.
5. Use Like for Simple, Natural Comparisons
Like is often the most natural choice when comparing people, objects, or situations.
Examples:
- Like her sister, Maria enjoys reading.
- Like the previous model, this device has a long battery life.
- Like the first student, the second student completed the task independently.
Instead of writing “Similarly to her sister, Maria enjoys reading,” you can write “Like her sister, Maria enjoys reading.”
The second sentence is shorter and more natural in everyday English.
15 Examples of Similar To vs Similarly To
These examples show how each expression works in context and how to improve awkward comparisons.
Using examples Similar to
- This painting is similar to the original.
- My new laptop is similar to the model my brother uses.
- Her opinion is similar to mine.
- The new building looks similar to the old library.
- The results are similar to those reported in the previous study.
- This recipe is similar to the one my grandmother makes.
- His teaching style is similar to that of his former teacher.
- The procedure is similar to the method described in the manual.
Usingexamples Similarly or Similarly to
- The first team performed well. Similarly, the second team achieved excellent results.
- The second student responded similarly to the first student.
- Both samples were processed similarly.
- The new machine operates similarly to the older model.
- The first company reduced its expenses. Similarly, its competitor lowered operating costs.
Examples Showing Better Comparison Structure
- Awkward: The fragments were obtained similarly to the sticks.
Clearer: The fragments were obtained similarly to how the sticks were obtained. - Awkward: The fragments were obtained in a way similar to the sticks.
Clearer: The process for obtaining the fragments resembled the process for obtaining the sticks.
These last examples illustrate an important principle: a sentence can be grammatically possible but still be difficult to interpret. Clear comparisons require parallel structure, especially in academic and scientific writing.
Common Mistakes When Using Similar To and Similarly To
Understanding common errors can help you choose the correct expression and communicate your intended meaning.
Mistake 1: Using Similarly Instead of Similar
Incorrect: This dress is similarly to mine.
Correct: This dress is similar to mine.
Why? The sentence describes the resemblance between two dresses, so it needs the adjective similar.
Mistake 2: Using Similar Instead of Similarly
Incorrect: The first team performed well. Similar, the second team achieved excellent results.
Correct: The first team performed well. Similarly, the second team achieved excellent results.
Why? The second sentence needs an adverb to connect the related statements.
Mistake 3: Comparing Different Elements
Awkward: The fragments were obtained in a way similar to the sticks.
Clearer: The fragments were obtained in a way similar to the way the sticks were obtained.
Why? The first version compares a method with physical objects. The revised version compares one method with another method.
This is an example of a parallelism problem. Parallel structure means that the elements being compared should have matching grammatical forms or clearly corresponding meanings.
Mistake 4: Assuming Similarly To Is Always Incorrect
Incorrect rule: You should never use similarly to.
Better rule: The expression can be grammatically correct, but its suitability depends on the sentence.
Example: The new system operates similarly to the previous system.
This is understandable and acceptable, although “The new system operates in a way similar to the previous system” may be preferable in some contexts.
Mistake 5: Using Similarly To When Like Is More Natural
Awkward: Similarly to her father, Ayesha enjoys gardening.
More natural: Like her father, Ayesha enjoys gardening.
Why? Like makes the direct comparison simple and clear.
Mistake 6: Confusing Similar With Identical
Incorrect assumption: Two similar objects must be exactly the same.
Correct understanding: Similar to means that two things share characteristics, not that they are necessarily identical.
For example, two phones may have similar designs but different cameras, prices, and battery capacities.
How to Remember the Difference
Use this simple memory trick:
Similar = resemblance.
The adjective similar describes how one thing resembles another.
Example: My shoes are similar to yours.
Similarly = comparable manner or situation.
The adverb similarly describes a comparable action or connects related statements.
Example: The first student completed the task. Similarly, the second student finished early.
Like = direct comparison.
Use like when comparing people or things in a straightforward way.
Example: Like her mother, she enjoys painting.
Parallel structure = compare like with like.
When comparing procedures, compare one procedure with another. When comparing results, compare one set of results with another.
Example: The process for obtaining the fragments resembled the process for obtaining the sticks.
This last rule is especially useful in academic writing, where an unclear comparison can change the meaning of a sentence.
Similar To vs Similarly To in American and British English
The grammatical distinction between similar to and similarly is essentially the same in American and British English.
Both varieties commonly use similar to to describe resemblance.
Examples:
- American English: The results are similar to those of the previous study.
- British English: The results are similar to those of the previous study.
Both varieties also use similarly to connect related statements.
Examples:
- American English: The first method worked well. Similarly, the second method produced good results.
- British English: The first method worked well. Similarly, the second method produced good results.
Neither variety requires a different grammatical rule for these expressions.
In both American and British English, similarly to may sound awkward when the intended comparison is not clearly expressed. For formal or technical writing, choose a construction that identifies exactly what is being compared.
Similar Words and Expressions
Several expressions can help you communicate comparisons more naturally.
Like
Like introduces a direct comparison between people, objects, or situations.
Example: Like her brother, she enjoys swimming.
Alike
Alike means similar or resembling one another.
Example: The twins look alike.
Similarly
Similarly means in a comparable way and commonly connects related statements.
Example: The first study reported positive results. Similarly, the second study found an improvement.
In a Similar Way
In a similar way describes an action or process that resembles another.
Example: The second sample was processed in a similar way.
Comparable To
Comparable to means similar enough to be compared, although the things may not be identical.
Example: The quality of this product is comparable to that of a more expensive model.
Resemble
Resemble is a verb meaning to look like or share characteristics with someone or something.
Example: This building resembles an old castle.
Remember that resemble does not normally take to after it. Say “This building resembles a castle,” not “This building resembles to a castle.”
In the Same Way
In the same way emphasizes that something happens or is done using the same or a comparable method.
Example: The researcher repeated the second procedure in the same way as the first.
Choose the expression that makes your intended comparison clear without adding unnecessary words.
Final Verdict: Which Is Correct, Similar To or Similarly To?
Both similar to and similarly to can be correct, but they are not interchangeable in every sentence.
Use similar to when describing a resemblance between people, things, ideas, characteristics, or procedures. For example, “The process for obtaining the fragments was similar to the process for obtaining the sticks.”
Use similarly when connecting related statements or describing comparable actions. For example, “The fragments and the sticks were obtained similarly.”
Use similarly to when the sentence structure supports an adverbial comparison and the meaning is clear. For example, “The new system operates similarly to the previous system.”
When comparing methods, procedures, or actions, make sure the sentence compares the correct elements. Instead of “The fragments were obtained in a way similar to the sticks,” write “The fragments were obtained in a way similar to the way the sticks were obtained.”
The best rule is simple: choose the expression that makes the comparison clear, natural, and grammatically appropriate.
Frequently Asked Questions
1. Is Similarly To Grammatically Correct?
Yes, similarly to can be grammatically correct when the sentence clearly compares actions, methods, or situations. However, it can sound awkward when the comparison is unclear. In many cases, like, similarly, or in a similar way is a more natural choice.
2. What Is the Difference Between Similar To and Similarly To?
Similar to is an adjective phrase used to describe resemblance between two things. Similarly to is an adverbial construction that can compare actions or situations. The best choice depends on the grammatical structure and what the sentence compares.
3. Is It Correct to Say the Fragments Were Obtained Similarly to the Sticks?
The sentence is grammatically possible, but it is awkward because it does not clearly express the intended comparison between procedures. A clearer version is: “The fragments were obtained similarly to how the sticks were obtained.” You could also write, “The process for obtaining the fragments resembled the process for obtaining the sticks.”
4. Can I Use Similarly at the Beginning of a Sentence?
Yes. Similarly can begin a sentence when you want to connect it with a related statement.
Example: “The first experiment produced positive results. Similarly, the second experiment showed improvement.”
A comma usually follows similarly when it functions as a sentence-opening transition.
5. Should I Use Similar To or Similarly To in Academic Writing?
Use similar to when comparing findings, theories, characteristics, or procedures. Use similarly to connect related findings or describe comparable actions. If you use similarly to, make sure the sentence clearly identifies the two elements being compared. Parallel structure is especially important in scientific and academic writing.
6. What Is a More Natural Alternative to Similarly To?
The best alternative depends on the intended meaning. Use like for direct comparisons, similarly to connect related statements, or in a similar way to when describing comparable methods. For scientific writing, explicitly comparing one process with another can provide the greatest clarity.
7. What Does Parallel Structure Mean in Comparisons?
Parallel structure means presenting comparable ideas in matching or clearly corresponding grammatical forms. For example, “The process for obtaining the fragments resembled the process for obtaining the sticks” clearly compares two processes. It is more precise than “The fragments were obtained in a way similar to the sticks,” which compares a procedure with an object.
Remember This
- Similar to: Describes resemblance between people, objects, ideas, results, or methods.
- Similarly: Connects related statements or describes comparable actions.
- Similarly to: Grammatically possible, but sometimes awkward or unclear.
- Like: Often the most natural choice for direct comparisons.
- In a similar way to: Useful for comparing methods, provided the comparison is clearly expressed.
- Parallel structure: Helps ensure that you compare the right things.
Before choosing an expression, ask yourself: What exactly am I comparing? If the answer is clear from the sentence, your wording is more likely to be effective.
Conclusion
Understanding similar to vs similarly to requires more than memorizing the difference between an adjective and an adverb. You must also consider sentence structure, natural English usage, and the relationship between the elements being compared. Similar to is the standard choice for describing resemblance, while similarly commonly connects related statements or describes comparable actions. The construction similarly to can be correct, but it is not always the clearest option.
For everyday English, use similar to for direct comparisons and similarly to connect related ideas. For scientific and academic writing, pay particular attention to parallel structure so that your sentence compares methods with methods, results with results, and actions with actions.
When a sentence sounds awkward, try rewriting it with like, in a similar way, or an explicit comparison between the two processes. Clear wording will make your writing more accurate, natural, and easier to understand.
