Today's words

After a stretch of disappointing words-of-the-day, I thought I'd hit the jackpot with today's Dictionary Devil puzzle, only to learn as I was working on it that I really already knew most of them, at least enough to recognize them enough to do the puzzle. The exceptions:

kokanee \koh KAN ee\ - a small landlocked sockeye salmon

If I'd ever heard this, I had completely forgotten it.

galop \GAL up, gal OH\ - a lively dance in duple measure; also :  the music of a galop

I'm pretty sure I'd heard of this one, at least.

The others, which all came back to me, were mangosteen, the original sense of pariah, pinchbeck and rowel.
