The English phrase 'be rude' often translates to an adjective (失礼な) or a verb phrase (失礼なことをする) rather than a single verb. Avoid literal translations like '無礼である' in casual speech, as they sound stiff.
The word 失礼 (しつれい) is also used as a set phrase meaning 'Excuse me' when entering a room, interrupting, or leaving early. This is not rude; it's polite. Context distinguishes the meaning.
Please stop asking such forward (rude) questions.
