How Will You Know Which Word to Choose?
Knowing whether to use affect or effect can be confusing, but we hope you'll now be able to make the right choice moving forward. When in doubt, consider whether you're expressing action. If so, you'll probably need to use the verb affect. If you're talking about an event that has caused change, you'll want to use the noun effect.
If there's one thing the English language excels at, it's producing exceptions to every rule. This holds true for the affect vs. effect grammar rules. But, starting with the part of speech (verb or noun) is a safe place to begin the battle between the two.
Here's our final tip: A is for action (affect); E is for end result (effect). Happy choosing!
