Is TSK a valid word?

TSK is the clicking sound people make with their tongue to show mild disapproval, often doubled as TSKTSK, which is valid too; TSK also works as a verb, so TSKED, TSKING and TSKS are valid. It has no vowels, and its T, S and 5-point K make it worth 7 before any bonus. Picture a grandmother shaking her head and saying tsk, tsk.

Before any bonus squares: T 1 + S 1 + K 5 = 7. On a double-word square that's 14, on a triple-word 21, and every letter bonus under one of these tiles is applied first.

Later in the game, put the K on a 3L square and TSK is worth 17 before any word bonus.

Place that one tile so it also forms a word in the other direction and both words score.

Swap any one letter of TSK and these are still words:

No other word in the list uses exactly the letters T, S and K.

TSK is the clicking sound of disapproval, as in “tsk tsk”. It also works as a verb.
