5 English Phrases Every Developer Needs for Code Reviews

Code reviews are one of the most communication-heavy parts of a developer's day. You're not just reading code — you're explaining why something should change, how you'd approach it differently, and what trade-offs you see.

The problem? Most developers can read English perfectly fine, but freeze when it's time to write a review comment. The feedback is there in your head, but the words come out awkward — or worse, too blunt.

Here are five phrases that'll make your code review comments clearer, more professional, and actually useful.

1. "Have you considered..."

When to use it: You see a potential issue or a better approach, but don't want to sound like you're telling the author what to do.

Example:

Have you considered using a Map here instead of an array? With 10k+ items, the lookup time difference would be noticeable.

Why it works: It opens a conversation instead of issuing a command. The author feels respected, not attacked. In many teams, this is the difference between a review that sparks good discussion and one that starts a flame war.

Avoid: "You should use a Map" — technically the same advice, but it reads like an order.

2. "Could you clarify..."

When to use it: You don't understand the reasoning behind a decision, and you want to learn — not criticize.

Example:

Could you clarify why you chose to handle this in the frontend rather than the backend? I might be missing context.

Why it works: It acknowledges that there might be context you don't have. Code reviews aren't just about finding bugs — they're about knowledge sharing. This phrase invites the author to explain their thinking, which benefits the whole team.

Pro tip: Pair it with "I might be missing context" — it signals intellectual humility and makes the other person more willing to engage.

3. "This works, but..."

When to use it: The code is correct, but you see room for improvement — readability, performance, or maintainability.

Example:

This works, but extracting this logic into a separate function would make it easier to test. Something like validateUserPermissions() would clarify the intent.

Why it works: Starting with "this works" validates the author's effort. Nobody wants to hear that their working code is wrong. The "but" pivot says: "you solved the problem, and here's how we can make it even better."

Avoid: "This is wrong" when the code actually works — it shuts people down.

4. "Nit: ..."

When to use it: It's a minor style issue — naming, formatting, a typo — and you want to signal that it's not a blocker.

Example:

Nit: userData could be userProfile to match the naming convention in the rest of the codebase.

Why it works: The "Nit:" prefix is universal shorthand in dev culture. It tells the author: "This is a nice-to-have, not a must-fix. Don't block your PR on this." It keeps reviews focused on what matters.

Bonus: Some teams use [nit] or [minor] — same idea, different format. Pick one and stay consistent.

5. "Great catch on..."

When to use it: The author fixed something you pointed out, or they caught an issue you missed. Positive reinforcement.

Example:

Great catch on the race condition — I hadn't thought about that edge case with concurrent requests.

Why it works: Code reviews are a two-way street. When you acknowledge someone's work, it builds trust. The next time you leave a critical comment, they'll be more receptive — because they know you're not just there to tear things down.

This one is underrated. Most review conversations are transactional: "fix this," "done," "approved." A genuine "great catch" breaks that pattern and makes the whole process less draining.

The Pattern Behind These Phrases

Notice what they have in common:

• They're questions, not commands. "Have you considered" beats "change this to."
• They acknowledge the author. Every comment starts from a place of respect.
• They're specific. Vague feedback like "this could be better" is useless. Each phrase above is tied to a concrete action.

Code reviews are a skill, and like any skill, they improve with practice. These five phrases won't make you a perfect reviewer overnight, but they'll make your comments something people want to respond to — not something they dread reading.
