Always double-check your word choice between "affect" and "effect". "Affect" is primarily a verb, while "effect" is primarily a noun. Use "effect" when you mean a result or consequence.

Common error

Don't use "affect" when you mean "effect" as a noun. Remember that "affect" is mainly used as a verb, while "effect" is mainly used as a noun. For example, instead of saying "The decision had a substantial affect", say "The decision had a substantial effect".
