Confused About When to Use 'Affect' vs 'Effect' in My Report

Asked bySam SentencePosted Mar 23, 2026 2:36 PM3 answers19 upvotesCanonical URL

I'm writing a report for my English class, and I keep getting stuck on whether to use 'affect' or 'effect.' For example, should I write, 'The new law will affect small businesses,' or 'The new law will effect small businesses'?

Also, in another part, I want to say, 'The main effect of the change was an increase in sales.' But now I'm second-guessing myself. I’d love some clarification on the difference between these two words, especially with examples like these.

To distinguish between 'affect' and 'effect,' start by identifying their most common patterns:

  • 'Affect' is usually a verb meaning 'to influence or change.'
  • 'Effect' is usually a noun meaning 'a result or outcome.'

Examples:

  • The noise will affect my concentration. (Will influence)
  • The effect of noise was a drop in productivity. (The result)

Practice suggestion:
Try writing two sentences in your report: one using 'affect' as a verb and another using 'effect' as a noun. Then, swap 'affect' and 'effect' to see if the meaning still makes sense. If it sounds wrong (e.g., 'The new law will effect small businesses'), double-check which form is needed. If you find yourself wanting to describe a result, use 'effect' (noun); if you mean to say something influences something else, go with 'affect' (verb).

Think of 'affect' and 'effect' as word pairs with similar sounds but different jobs:

  • 'Affect' (Verb): To produce a change in something. E.g., How will the drought affect crop yields?
  • 'Effect' (Noun): The change that has occurred. E.g., The most noticeable effect of the drought was food scarcity.

Correction Tip: If you're trying to describe what something DOES (action), check if 'affect' fits. If you're discussing what happened or what was produced, 'effect' is likely correct.

Quick self-check: For each sentence in your report, ask: Am I describing an action (use 'affect') or a result (use 'effect')?

A helpful strategy is swapping the words in your sentence to see which one correctly fits the context:

  • Original: Rising temperatures will affect polar bear populations.

    • Try swapping: Rising temperatures will effect polar bear populations. (This sounds awkward, so 'affect' is correct.)
  • Original: The effect of rising temperatures was a decline in polar bear numbers.

    • Try swapping: The affect of rising temperatures was a decline in polar bear numbers. (This is incorrect; 'effect' as a noun is needed.)

Practice: Take two sentences from your report and do a word swap test. If using 'affect' makes it a statement of action and 'effect' makes it a statement of resulting outcome, you've likely used them correctly.
