Is 苦手 etymologically related to 苦い？ Does the former derive from the latter? Does the fact that they have the same root kanji make this obvious, or is there something about 手 that also gives me information about the word? I'd be doubly happy to learn that there's some pattern I haven't yet learned.
I don't own the Nihongogen, so I can't look it up there, and Wiktionary doesn't connect the two.
I'm guessing I'm asking something fairly obvious if I keep learning, but I admit my curiosity is getting the better of me now.
