Do I always have to shake my head when signing 'not'?
Yes! In ASL, shaking your head is a crucial Non-Manual Marker (NMM) for negation. Even if you sign the word perfectly with your hands, forgetting the headshake can make your sentence look unnatural or cause the viewer to miss the negative meaning entirely.
What exactly is an open 'A' handshape?
An open 'A' handshape is made by forming a fist like the ASL letter 'A', but extending your thumb outward instead of resting it flat against your index finger. For the sign 'not', the pad of this extended thumb is what touches the bottom of your chin.
Where does the word 'not' go in an ASL sentence?
In ASL, 'not' usually comes right before the verb or adjective you are negating, such as signing 'NOT LIKE' or 'NOT COLD'. Depending on the context, it can also be placed at the very end of the sentence to add emphasis to the denial.
