English has a lot of commonly confused words. They either look alike, sound alike or, worst of all, look and sound alike but have completely different meanings. Other words look and sound different but are similar in meaning, and it’s hard to determine which is the correct one in a given context. Hopefully the following list of pairs of commonly confused words will help you keep them straightened out.
Accept (verb) - to receive
Except (conjunction) - apart from; otherwise than; were it not true
Affect (verb) - to have an effect on; influence; produce a change in; to stir the emotions

Bad (adjective) - not good
Badly (adverb) - not well; in a bad manner; harmfully; incorrectly; wickedly; unpleasantly
*Here, a note. Adjectives generally describe nouns, so even if you use the word “bad” following a verb in a sentence, if it’s meant to describe the thing itself, then use the adjective. “Bad” here means the same as “rotten,” “rancid” or “stinky,” all of which are adjectives. If you can replace “bad” with another adjective and still have a sentence that makes sense, then you know that “bad” was the correct choice. Adverbs often describe the manner in which something is done. To say, “your feet smell badly” is to say that your feet are inhaling through the nose and perceiving odors, and that they’re going about it all wrong.
