What is the difference between "affect" and "effect"?

The distinction between "affect" and "effect" is fundamental in understanding their meanings and grammatical roles in the English language. "Affect" is primarily used as a verb and means to influence or make a change in something. For example, when we say that the weather can affect our mood, we are indicating that the weather has the power to influence how we feel.

On the other hand, "effect" is used as a noun and refers to the outcome or the result of a particular change. For example, when we discuss the effects of climate change, we are referring to the consequences or outcomes stemming from changes in the climate.

This correct answer illustrates that "affect" is the action of influencing, while "effect" describes what happens as a result of that influence. This clear distinction is crucial for proper usage in both spoken and written English, helping convey ideas accurately.
