Trimmed small bit (7)
I believe the answer is:
snipped
'trimmed small bit' is the definition.
'snipped' can be an answer for 'trimmed' ('snip' can be a synonym of 'trim'). I am not sure about the 'small bit' bit.
'trimmed small bit' is the wordplay.
'trimmed small' becomes 's' (abbreviation - e.g. clothes size. I am not sure about the 'trimmed' bit.**).
'bit' becomes 'nipped' (nipping is a kind of biting).
's'+'nipped'='SNIPPED'
Can you help me to learn more?
(Other definitions for snipped that I've seen before include "Trimmed" , "cut off" .)
