Affect and Effect are homonyms, in which there is just one difference in their spellings, i.e. in their first letter, but when you go through their meanings, you will find that the difference between them is not slight. The term ‘affect’ is most commonly used as a verb which means “to influence” or “to change”.
On the other hand, the word ‘effect’ is primarily used as a noun and means “consequence”, “aftermath”, “result of an action” or “reaction”. Nevertheless, both can be used as a noun and also as a verb, and so it is needless to say that their meanings differ when they are used as different parts of speech.
Let’s look at these examples to understand the difference correctly:
