Japanese has a word for 'part-time job' borrowed from the German word for 'work'

Languages constantly borrow words from each other, usually without translating them: Japanese 'arubaito' comes from German 'Arbeit', English 'kindergarten' and 'sushi' stayed foreign words wholesale, and Finnish 'pankki' comes from Swedish for 'bank'. Linguists call these loanwords, and nearly every language has thousands of them, often without speakers noticing.
