Affect v EffectJune 14, 2013
Based on a recent writing tip I wrote for my work colleagues.
Joe asked: Is it ‘result in adverse affects’ or ‘result in adverse effects’? Good question, Joe – and the answer is ‘effects’ in your example (‘adverse’ is the adjective qualifying the noun ‘effects’).
Affect/effect are a commonly misused, so here’s some guidance: Generally, affect is a verb (past tense: affected) and effect is a noun.
Mignon Fogarty (Grammar Girl; http://grammar.quickanddirtytips.com/affect-versus-effect.aspx) has this to say about each:
When Should You Use Affect? Affect with an a means “to influence” as in “The arrows affected Ardvark” or “The rain affected Amy’s hairdo.” Affect can also mean, roughly, “to act in a way that you don’t feel” as in “She affected an air of superiority”.
When Should You Use Effect? Effect with an e has a lot of subtle meanings as a noun, but to me the meaning “a result” seems to be at the core of all the definitions. For example, you can say “The effect was eye-popping” or “The sound effects were amazing” or “The rain had no effect on Amy’s hairdo”.
And our own Macquarie Dictionary has these definitions with examples of usage:
