Talk? Yes - to the point! (3)
I believe the answer is:
jaw
'talk?' is the definition.
(jawing is a kind of talking)
'yes to the point' is the wordplay.
'yes' becomes 'ja' (I am not sure about this - if you are sure you should believe this answer much more).
'to the point' becomes 'w' (W is an example).
'ja'+'w'='JAW'
Can you help me to learn more?
(Other definitions for jaw that I've seen before include "Facial bone" , "It frames the mouth and holds the teeth" , "Talk; bone" , "Talk incessantly" , "Natter - mandible" .)
