Select the correct ANTONYM for: Rude

Answer: Decent is the correct antonym of Rude.

Key idea: An antonym is a word with the opposite meaning.

• Why "Decent" is correct: "Rude" means impolite or offensive; "Decent" means polite, respectable, or proper, which directly contrasts with "rude."

• Why "Obscene" is incorrect: "Obscene" means indecent or offensive and is similar in meaning to "rude," not opposite.

• Why "Blunt" is incorrect: "Blunt" means frank or direct. It may sometimes come across as rude, but it is not the opposite of being rude.

• Why "Abusive" is incorrect: "Abusive" refers to insulting or harmful language, which is similar to "rude," not its antonym.

Therefore, "Decent" best fits the requirement of being the opposite of "rude."
