年寄り | (’70s and up) This isn’t rude per se, but if you want to dismiss or belittle what an old fart just said, this is the word you use. $$$ |
老人 | (’70s and up) old person. |
年をとった | (’70s and up) just like 老人 but it’s an adjective. |
年輩 | This is the most polite – you can even use it for someone in their ’60s – but it’s so formal you can’t say ‘年輩の人’, you have to say ’年輩のカタ’. |
