Both effect and affect can swap roles at times, with effect acting as a verb and affect as a noun. Take a look at some examples below:

- Despite the good news, her affect remained unchanged.

A prevalent mistake is simply using the wrong word due to their similar spelling. To steer clear of this, remember that affect with A for Action is usually a verb, while effect with E for End result is commonly a noun.
Contextual Mistakes: Misusing Effect and Affect
Sometimes people can misuse these words in a sentence. The key to avoiding this blunder is understanding the context and the role of the word. Ask yourself, is it indicating a result (effect) or an influence (affect)?

Incorrect: The medicine has many side affects.
Correct: The medicine has many side effects.
Here, 'effects' should be used because it refers to the results or outcomes of taking the medicine. 'Affect' as a noun is a psychology term that refers to emotional states, which isn't the intended meaning in this case.
Incorrect: The new policy did not effect the citizens much.
Correct: The new policy did not affect the citizens much.
'Affect' should be used in this sentence because it means to influence or have an impact on. 'Effect' as a verb means to cause or bring about, which is not the intended meaning in this context.
