There is a facial expression that is sometimes called a "wh-q" expression. It is the type of facial expression you should use when asking questions that have an answer other than yes or no. Generally these questions start with the letters "wh" as do the signs WHO, WHAT, WHEN, WHERE, WHY...so you can see why we call this expression a "wh" question expression. Expressing the concept of "WHAT" has more to do with your facial expression than your hands. For example, if I pointed to my watch and used the "wh-q" facial expression it would mean that I'm asking you "What time is it?" You've probably already used this sign many times in your life.

WHAT ("huh" version)

In the picture below I'm doing a general gesture for "what" while using the WHAT facial expression.

Hold your relaxed "5" hands in front of you. Hunch your shoulders a bit. Jut your head forward a bit.

Use a WH-Q (wh-question) facial expression. The hands move slightly forward and to the sides.



Here is a variation of the sign "WHAT" that is made by extending your base hand outward. Starting near the thumb, drag the tip of your index finger downward, across your palm. Note: I don't teach this sign in my "ASL" classes. Instead I use the general version (above). But I'll show this other version to you so you'll be able to recognize it if you see it.
