What does 춘 mean?

 ANSWER: "Spring," of course.

Every word in my Korean-English dictionary that starts with the syllable 춘, except for two (춘부장 椿府丈 / 춘사 椿事), are Sino-Korean words that start with the Chinese character that means "spring" (春). And as far as I know, there are no pure Korean words that start with 춘.  Also, there are only two other 춘 characters (椿, 杶) in my Chinese character dictionary, and they both refer to the same tree, a Toona sinensis, commonly called Chinese mahogany or Chinese cedar. So, if you see a Korean word that starts with the syllable 춘, it is almost certain to be using the 춘 (春) that means "spring."
