Affective vs. Effective | Difference & Example Sentences

Affective and effective are two adjectives that are commonly confused.

  • Affective (pronounced [af-ek-tiv]) describes something that influences or causes feelings or emotions. It can also describe how these emotions are expressed.
  • Effective (pronounced [if-ek-tiv]) instead signifies that something is having an effect (especially the effect that was hoped for).
Examples: “Affective” in a sentence Examples: “Effective” in a sentence

The best approach is to bear in mind that effective is a much more commonly used word than affective. If the sentence doesn’t immediately relate to feelings or emotions, the correct word is effective.

The distinction made here is the same as that between the related words affect and effect—where, again, affect (as a noun) is much rarer than effect.
