When spoken out loud, affective and effective can be hard to differentiate. That’s probably why they’re often used interchangeably, both in speech and in writing.
But despite just a single vowel separating them, these two adjectives carry quite different meanings. Read on for a full explanation and some helpful tips for remembering the difference.
Affect vs. Effect
To understand the difference between affective and effective, you’ll first want to review the difference between affect vs. effect.
Affect can be used as a noun, which refers to an emotion or feeling that influences behavior.
As a verb, however, affect means to impact or make a difference to something else. In other words, as a verb, affect leads to effects (results).
Effect is most commonly used as a noun to refer to results (think cause and effect).
When used as a verb, effect means “to make happen.” For example, “The politician promised to effect great change.”
Affective is an adjective that describes a thing or action that relates to feelings, moods, or attitudes.
Affective comes from the noun affect, not the verb. The noun refers to an emotion or feeling that influences behavior (see the full explanation above).
The term affective is most frequently encountered in psychology-related writing, such as studies on emotions or mood disorders. As far as everyday communication, it’s more likely that effective is the word you’re looking for. You’ll find its definition below.
Effective is an adjective that describes a thing or process that successfully produces the intended result, or effect.
This is the definition that you will probably encounter most often, although “effective” can also be used as a synonym for “virtual” or “practical” (e.g., “The tools were effectively useless after the rain.”)
How to Remember Affective vs. Effective
An easy way to remember that affective deals primarily with emotions is through its close connection to affectionate. When someone is affectionate toward you, they express fondness.
However, unless you’re talking about psychology, affective is pretty rare in every day language, so it’s more likely that the word you need is effective.
See the examples below to get a better understanding of how these two words are used.
