Grammar Tip: Affect vs. Effect
These two words can be confusing because both can be used as a noun or a verb. Affect as a verb means to influence while effect as a verb means to cause or to bring about.
• Ex. The rain affected the game.
• Ex. The new principal will effect big changes in the school.
When using as a noun, effect is the best option. It means result or consequence. Affect, as a noun, is rarely used. If it is used in this form, it is used in the field of psychology to refer to an emotion.
• Ex. The effect of the changes was felt by everyone.
