Common Mistakes When Using ‘similarly’ in a Sentence

The most common mistake when using “similarly” is treating it as a simple synonym for “also” or “too” without understanding its specific function: it signals a comparison of manner, process, or characteristic between two actions or situations. Many learners place it incorrectly in a sentence, use it where a different connector is needed, or forget to maintain parallel structure. This guide explains exactly how to use “similarly” correctly in academic and everyday writing.

Quick Answer: How to Use ‘similarly’ Correctly

“Similarly” is a conjunctive adverb that shows two things are alike in a specific way. Use it at the beginning of a sentence followed by a comma, or in the middle of a sentence between two clauses with a semicolon before it and a comma after. It works best when you have already described one item or action and want to add a second that shares a key feature.

Correct: “The first experiment measured reaction time. Similarly, the second experiment tested response accuracy.”

Incorrect: “I like coffee similarly tea.” (Missing verb and structure)

Understanding the Core Function of ‘similarly’

“Similarly” belongs to a group of words called comparative connectors. Its job is to show that two things are comparable in a specific way. Unlike “also,” which simply adds information, “similarly” explicitly draws a parallel. This makes it especially useful in academic writing, research papers, and formal reports where you need to show relationships between ideas.

Formal vs. Informal Tone

“Similarly” is primarily a formal or neutral word. You will find it often in:

• Academic essays and research papers
• Business reports and proposals
• Formal emails and professional correspondence
• Legal or technical documents

In casual conversation or informal emails, native speakers usually prefer “likewise,” “in the same way,” or simply “also.” For example, in a text message you might say “I had a great time too” rather than “Similarly, I enjoyed the evening.”

Common Mistakes with ‘similarly’

Mistake 1: Using ‘similarly’ as a conjunction

“Similarly” is not a conjunction like “and” or “but.” It cannot join two clauses directly without proper punctuation.

Incorrect: “The data was collected in January similarly the survey was conducted in February.”

Correct: “The data was collected in January. Similarly, the survey was conducted in February.”

Correct: “The data was collected in January; similarly, the survey was conducted in February.”

Mistake 2: Placing ‘similarly’ in the wrong position

When “similarly” appears in the middle of a sentence, it must follow a semicolon and be followed by a comma. Placing it after a comma without a semicolon creates a comma splice.

Incorrect: “The company expanded its online presence, similarly it hired more remote staff.”

Correct: “The company expanded its online presence; similarly, it hired more remote staff.”

Mistake 3: Using ‘similarly’ when you mean ‘also’

If you are simply adding information without drawing a comparison, “also” is more appropriate. “Similarly” forces a comparison that may not exist.

Incorrect: “The restaurant serves Italian food. Similarly, it has a nice view.” (The view is not a comparison to the food.)

Correct: “The restaurant serves Italian food. It also has a nice view.”

Mistake 4: Forgetting parallel structure

When you use “similarly,” the two items being compared should have parallel grammatical structure. If the first item is a noun phrase, the second should also be a noun phrase.

Incorrect: “The first chapter discusses economic theory. Similarly, analyzing historical data is the focus of chapter two.” (Mismatched structure)

Correct: “The first chapter discusses economic theory. Similarly, the second chapter analyzes historical data.”

Natural Examples of ‘similarly’ in Context

Academic Writing

“The study found that students who attended tutoring sessions scored higher on exams. Similarly, those who participated in study groups showed improved performance.”

Business Email

“Our marketing team has increased social media engagement by 30%. Similarly, the sales department has seen a 15% rise in conversions.”

Everyday Conversation (Formal Context)

“I prefer to finish my work before taking a break. Similarly, my colleague likes to complete tasks before lunch.”

Research Paper

“The control group exhibited no significant change. Similarly, the placebo group showed minimal variation.”

Better Alternatives to ‘similarly’

Depending on your context, you might choose a different word or phrase:

• Likewise – Best for formal speech and writing when you want a slightly more natural flow.
• In the same way – Useful when explaining a process or method step by step.
• By the same token – Adds a logical connection, often used in arguments.
• Correspondingly – Very formal, used in academic or technical writing to show a direct relationship.
• Equally – Works when emphasizing that two things are of equal importance or value.

When to Use ‘similarly’ (and When Not To)

Use ‘similarly’ when:

• You have already described one item or action and want to add a second that shares a key characteristic.
• You are writing a formal document, essay, or report.
• You want to emphasize the comparison between two things.

Do not use ‘similarly’ when:

• You are simply adding information without comparison (use “also” or “in addition”).
• You are writing a casual text or informal email (use “too” or “likewise”).
• The two items are not truly comparable in the way you are describing.

2. Is “similarly” the same as “likewise”?

They are very similar, but “likewise” can also be used as a response in conversation (e.g., “Nice to meet you.” “Likewise.”). “Similarly” is rarely used this way. In writing, they are often interchangeable.
