Is QIVIUTS a valid word?

QIVIUTS is the plural of QIVIUT, the warm underwool of the musk ox, from an Inuit word. It is a seven-letter play, so from your own rack it is a bingo, and the Q and V give it a strong letter score besides. More often, you will see the S hook: when QIVIUT is already on the board, an S on the end makes QIVIUTS and counts the Q again. Qiviut is warmer than sheep's wool and does not shrink in water, which is why it is so prized. Knitters treasure qiviut yarn, and a single scarf can cost a great deal. A musk ox sheds its qiviut each spring, and people gather the soft tufts by hand.

Before any bonus squares: Q 10 + I 1 + V 4 + I 1 + U 1 + T 1 + S 1 = 19. On a double-word square that's 38, on a triple-word 57, and every letter bonus under one of these tiles is applied first.

Later in the game, put the Q on a 3L square and QIVIUTS is worth 39 before any word bonus.

No other word in the list uses exactly the letters Q, I, V, I, U, T and S.

QIVIUTS is the plural of QIVIUT, musk-ox wool. Seven tiles, with a Q and a V.
