HOW DO I KNOW WHEN TO USE EFFECT OR AFFECT IN A SENTENCE

Answer 1

Short answer: use affect when you mean the verb “to influence” and effect when you mean the noun “the result.”

Quick rules and tricks
- Affect (usually) = verb. It means “to influence.” Example: The storm will affect travel plans.
- Effect (usually) = noun. It means “the result.” Example: The storm had a major effect on travel.

Memory trick: RAVEN — Remember: Affect = Verb, Effect = Noun.

Substitution test
- If you can replace the word with “influence,” it should be affect (verb).
- If you can replace it with “result” or “outcome,” it should be effect (noun).

Common exceptions and notes
- Effect can be a verb meaning “to bring about” (formal): They hope to effect change. (Here effect = cause to happen.)
- Affect can be a noun in psychology meaning “observable emotion” (rare): The patient displayed a flat affect.
- Don’t confuse effective (successful) with affective (relating to emotion).

Examples (right vs wrong)
- Right: The new policy will affect employee schedules. (verb)
- Right: The new policy had a big effect on schedules. (noun)
- Right (verb effect): The committee effected a policy change. (brought it about)
- Right (noun affect): The therapy improved the patient’s affect. (psych term)
