Generally speaking, "affect" is used as a verb and means when one thing causes a change in another, while "effect" is a noun and is a result of a change. Here is an example: The gravitational force of the moon AFFECTs the ocean's tides. The EFFECT of the moon's gravitational force can be observed in relation to its distance from the earth. Another example: His bad mood is AFFECTing my good mood. I felt the EFFECT of his bad mood on my mood. Hope this helps

Taily, To put it in simplistic terms, "affect" means that something undergoes a change due to something else while "effect" is the end result of a change. Example: Your diet affects your health. (Your health undergoes a change due to your choice of diet.) The effect of stress is poor health. (The end result of stress is poor health.) A poor diet affects your health, with poor health being the effect. Hope this helps.

Hello. In general, 'affect' is a verb and 'effect' is a noun. There are some exceptions though (https://www.vocabulary.com/articles/chooseyourwords/affect-effect/) but I really doubt you'll need to worry about them.
