敢えて is a formal adverb that expresses that someone does something deliberately, even though it might be difficult, risky, or not expected. It often carries a nuance of 'daring to' or 'bothering to' do something that others might avoid. For example, you might use it when someone asks a question they know could be awkward, or when you choose a more challenging path on purpose.

In negative sentences, 敢えて…ない means 'not particularly' or 'not go out of one's way to do something'. This is a common usage where the speaker indicates they don't feel the need to do something.

Because it is a formal, written-style word, it is more common in essays, news, and speeches than in everyday casual conversation. In speech, you might hear it in formal settings or when someone is being emphatic.
