I'm a compulsive crossword puzzle solver. I don't know what the phenomenon is, but filler words seem to be in vogue for a while, then disappear from the puzzlemakers' lexicons. Currently "iatric" with a definition "of or relating to medicine" is much in vogue.

I wonder what causes this phenomenon. And someone I know is a former puzzlemaker. I must track him down and ask.
