I want to start a new running segment on this blog called "Random Kanji of the Day."
Today's Kanji is 用.
It is pronounced "you (like yo, but long o)"
It means "task or business," but also "service or duty." Keyword: duty.
Interestingly one of the other definitions in the dictionary : "call of nature, or excretion."
So apparently you can say "do your duty" in English and Japanese.
