Made a gesture, and added name (6)
I believe the answer is:
signed
I believe this is a double definition.
'made a gesture' is the first definition.
(as in sign language)
'added name' is the second definition.
(signed one's name)
'and' acts as a link.
(Other definitions for signed that I've seen before include "Gestured with meaning" , "Inscribed - endorsed" , "Authorised (in writing)" , "Wrote one's name" , "Put one's name to" .)
