Objectionable means offensive, inappropriate, or unacceptable in a way that makes people want to object or complain about it. When something is objectionable, it bothers people enough that they feel they need to speak up against it.

A teacher might find a student's rude joke objectionable because it crosses the line of what's appropriate in class. A movie rating system might label certain content as objectionable for young viewers because it contains violence or scary scenes unsuitable for children. Parents might find a song's lyrics objectionable if they include curse words or disrespectful messages.

What makes something objectionable depends partly on context and values. Language that's objectionable in a classroom might be fine on a sports field. Content that's objectionable for a children's book might be perfectly acceptable in an adult novel. The key is that objectionable things violate standards of decency, appropriateness, or acceptability that matter in a particular situation.
