The most common mistake with ‘however’ in academic writing is using it as a simple substitute for ‘but’ without understanding its punctuation rules and formal tone. In academic contexts, ‘however’ is a conjunctive adverb that requires a semicolon or period before it and a comma after it, not a comma alone. This guide explains the exact rules, shows you how to fix errors, and gives you natural alternatives for essays, reports, and formal emails.
Quick Answer: How to Use ‘however’ Correctly
In academic writing, use ‘however’ to show contrast between two complete sentences. Place a semicolon (;) before it and a comma (,) after it. Alternatively, start a new sentence with ‘However,’ followed by a comma. Never join two sentences with only a comma before ‘however’—that creates a comma splice, a common error in formal writing.
Why ‘however’ Causes Problems
Many learners treat ‘however’ like ‘but’ because both words express contrast. However, they work differently. ‘But’ is a coordinating conjunction that joins two clauses with just a comma. ‘However’ is a conjunctive adverb that needs stronger punctuation. Using ‘however’ incorrectly can make your academic writing look careless, especially in essays, research papers, or formal emails to professors.
Formal vs. Informal Tone
‘However’ is more formal than ‘but’. In academic writing, ‘however’ adds a sophisticated tone, but only when used correctly. In informal conversation or emails to friends, ‘but’ or ‘though’ sounds more natural. Overusing ‘however’ in casual contexts can make you sound stiff or unnatural.
Comparison Table: ‘however’ vs. ‘but’
| Feature | ‘however’ | ‘but’ |
|---|---|---|
| Part of speech | Conjunctive adverb | Coordinating conjunction |
| Punctuation needed | Semicolon or period before; comma after | Comma before (when joining two clauses) |
| Formality | Formal | Neutral to informal |
| Position in sentence | Beginning, middle, or end | Only between two clauses |
| Common mistake | Comma splice (e.g., “I studied, however I failed.”) | Missing comma (e.g., “I studied but I failed.”) |

Common Mistakes with ‘however’
Below are the three most frequent errors learners make. Each mistake is followed by the correct version.
Mistake 1: Comma Splice
Incorrect: The theory is widely accepted, however new evidence challenges it.
Correct: The theory is widely accepted; however, new evidence challenges it.
Explanation: A comma alone cannot join two independent clauses with ‘however’. Use a semicolon or start a new sentence.
Mistake 2: Missing Comma After ‘however’
Incorrect: The results were unexpected however they were consistent.
Correct: The results were unexpected; however, they were consistent.
Explanation: Always place a comma after ‘however’ when it introduces a contrasting clause.
Mistake 3: Using ‘however’ Like ‘but’ in the Middle
Incorrect: The study was thorough however limited by funding.
Correct: The study was thorough but limited by funding.
Explanation: ‘However’ cannot directly connect a subject and a verb phrase. Use ‘but’ for shorter, simpler contrasts.
Better Alternatives to ‘however’
Sometimes ‘however’ is not the best choice. Here are alternatives for different contexts, with notes on formality and nuance.
- Nevertheless – More formal than ‘however’. Use it when the contrast is strong and you want to emphasize persistence. Example: “The evidence was inconclusive; nevertheless, the committee proceeded with the recommendation.”
- Nonetheless – Similar to ‘nevertheless’, but slightly less common. Good for academic writing. Example: “The budget was cut; nonetheless, the project was completed on time.”
- On the other hand – Use when presenting two balanced sides of an argument. Example: “Online courses offer flexibility. On the other hand, they require strong self-discipline.”
- Yet – A conjunction similar to ‘but’, but slightly more formal. Example: “The proposal was innovative yet impractical.”
- Although / Even though – Use at the beginning of a dependent clause. Example: “Although the results were promising, further testing is needed.”
When to Use ‘however’ vs. Alternatives
Use ‘however’ when you want a formal, clear contrast between two complete thoughts. Use ‘nevertheless’ or ‘nonetheless’ when the contrast involves overcoming an obstacle. Use ‘on the other hand’ when comparing two equal perspectives. Use ‘although’ when the contrast is within a single sentence.

FAQ: Common Questions About ‘however’
1. Can I start a sentence with ‘however’?
Yes, in academic writing, starting a sentence with ‘However,’ is correct and common. It adds emphasis to the contrast. Example: “The initial results were positive. However, further analysis revealed several flaws.”
2. Is it okay to use ‘however’ at the end of a sentence?
Yes, but it is less common in formal writing. When placed at the end, it often softens the contrast. Example: “The plan was ambitious. It succeeded, however.” This works better in informal or narrative contexts.
3. What is the difference between ‘however’ and ‘but’ in academic writing?

4. Can I use ‘however’ twice in one paragraph?
Yes, but avoid overuse. Using ‘however’ more than once or twice per paragraph can make your writing repetitive. Vary your transitions with alternatives like ‘nevertheless’, ‘on the other hand’, or ‘although’. For more transition word options, visit our Linking Words by Purpose section.
