In a conversation today, somebody said:
× After you retire your company, where will you live?
○ After you retire from your company, where will you live?
It's really tricky to know when a preposition is necessary in English. My suggestion is to memorize sets, like the one above:
- retire from [company]
It works the other way, too. Sometimes Japanese use a preposition when one isn't necessary.
× Have you asked to your friends where they want to retire?
○ Have you asked your friends where they want to retire?
I just visited Australia. It's a nice place, but I am not sure that I would retire there. Even if someone offered me a really cushy job there...
× I'd have to retire from my current job.
○ I'd have to quit my current job.
We usually only use "retire" when talking about someone who doesn't plan to work anymore, usually because of age.
The problem is that I really like my job and life in Tokyo! However, I did eat some nice food like these curries in Sydney. When I really do retire, I hope I can eat good food like this every day.
