Word in a Word

Recently I've been doing the Words in a word puzzles from the newspaper. These puzzles give you one word and your goal is to find as many Scrabble words four letters or more. You don't count words that get four letters by adding an S and only count one form of a verb. For a guy with a pretty decent vocabulary, I'm pretty terrible at this game. For example you can get 22 words out of CLIPPER. I got 10.

Today's word is SINUATE, which has 37. I've got 25-29 depending on how many I can get the judge to okay.
