Not at all forward
I believe the answer is:
shy
'not at all forward' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for shy that I've seen before include "Recoil" , "Timid (around people)" , "Timid and self-conscious" , "'Lacking self-confidence, timid (3)'" , "Nervous with others" .)
