Do I need to sign the words 'what', 'are', 'you', and 'doing' separately?
No, you do not! In ASL, the single sign 'DO-DO' combined with furrowed eyebrows translates the entire English phrase 'what are you doing' or 'what do we do'. ASL is a distinct language and does not translate English word-for-word.
Why do I have to furrow my eyebrows?
In ASL, facial expressions serve as grammar. Furrowed eyebrows are the grammatical marker for 'wh-questions' (questions asking who, what, where, when, why, or how). It signals to the other person that you expect an informational answer, not just a 'yes' or 'no'.
Can this sign just mean 'do'?
Yes, depending on the context and your facial expression, this sign can mean 'do', 'action', or 'activity'. However, when placed at the end of a sentence with furrowed eyebrows, it specifically asks 'what are you doing?' or 'what should I do?'.
