That last one turns up as an element in many compounds, but it's disconcerting to find it alone. Read ji, ni, shikashite, shikamo, nanji etc. You get it at level 1 of the JLPT, or you did in my day. Means 'then, and, but' in ordinary Chinese and a high-falutin' version of same in Japanese. Since it took me a while to get to level 1, for kanji memorization purposes I'd always thought of it as a rake, 'cause that's what it looks like. (Maybe. I think I first remembered it as umbrella, that being what you require when it rains: 需.)
Mr. Karlgren informs me its very oldest meaning, maybe from the oracle bones themselves, was 'beard.' He also tells me there's a hanzi that means 'play, sport'- 耍, which is 而 + 女, a woman wearing a beard. Cosplay, obviously, as preserved in the language since at least 200 BC.
Do I have a geek tag? I think I need one.
