I'd like to hire elves if I could, but It's difficult because of the language barrier.
It's hard to put into words, but Koichi is a very special person to me.
I was at a loss for words.
A leaf of the things you say is like a leaf from a tree of speaking. That leaf is a part of the whole language, it is a single word, though it can add up to be a language or manner of speech.
The reading for 言 is one you haven't learned. It's kind of an exception, in fact, though you might see it from time to time. You'll want to imagine yourself playing a koto (こと). Each strum of the instrument sends forth several words from its strings, flying at the person you're talking to. You speak your words via music, specifically the koto (so think about using other instruments as well to communicate... they just don't work).
