無理: impossible. The Japanese adjectival noun '無理 (むり)' means 'impossible' or 'unreasonable'. It is often used to describe situations, requests, or actions that are beyond one's capability or are too demanding. It can also imply that something is forced or done against one's will. For example: It's impossible to finish this by tomorrow「これを明日までに終わらせるのは無理だ」(これをあしたまでにおわらせるのはむりだ). Don't push yourself too hard; it's unreasonable「無理をしないで」(むりをしないで). The word can also be used to describe something that is physically or mentally straining, as in '無理な要求 (むりなようきゅう) (unreasonable demand)'.
