How to tell them apart
Both words stress FEKT. Start affect with a relaxed “uh” and effect with a short “ih,” but do not force the contrast: many speakers reduce both unstressed vowels, so grammar and context carry much of the difference.
Direct answer
What is the difference?
Use affect when something changes or influences something else. Use effect for the result that follows. There are less common exceptions—affect can name an observable emotional expression, and effect can mean “to bring about”—but the verb-versus-noun rule covers most everyday sentences.
