Can you use the row the card is in as a clue?
No. First entry under &quot;Firm Rules&quot;

Your clue must be about the meaning of the words. You can't use your clue to talk about the letters in a word or its position on the table.

I agree with a comment on another answer to keep the firm rule in place; as position clues can be used on every board, the game will become repetitive if they're allowed.
