Scrabble Word of the Day -- SLAP???

So you've got the letters S L A and P on your rack and you know you can at least play PA, PAS, PAL, PALS, LAP, LAPS, SAP, SLAP ... and any more I'm not thinking of at the moment.

Of course this assumes that you're willing to use an "S" without scoring big, or that you're playing a triple-word in two directions or something along those lines. But let's take a look at one more thing.

With those letters, you can also spell "PSAL". This is not a word in itself, but there a plenty of letters you can add to this (with tiles from the board or your rack) to finish a longer word. You've got:

PSALM
PSALMIC
PSALMIST
PSALMODY
PSALTER
PSALTERY
PSALTRY

This is just a few of the words that start with PS (including PSI) and, surprisingly, PT. You might whip out that old Scrabble dictionary and see just what else is available with these unusual word beginnings.
