The most common non-manual marker of (verbal) negation in TİD is a single backward head tilt, ‘ht-b’. It is usually accompanied by eye-brow raise. When this non-manual marker cooccurs with the free morpheme not, it spreads only over not.
ht-b
sıck^not
‘(He) is not sick.’
When it cooccurs with the cliticized not, then its scope usually covers not and the verbal stem.
ht-b
know^not
‘(I) don’t know.’
Another verbal negative form is puffed cheeks. This non-manual occurs with perfective verbs.

coca-cola drınk
‘(I) didn’t drink coca-cola.’
