Perhaps it’s barely taken off (3)
I believe the answer is:
kit
'barely taken off' is the definition.
I can't judge whether this defines the answer.
'perhaps it's' is the wordplay.
'perhaps' becomes 'k' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'it's' becomes 'it' (I've seen this in other clues).
'k'+'it'='KIT'
Can you help me to learn more?
(Other definitions for kit that I've seen before include "Equipment; young ferret" , "Set - uniform - gear" , "Young beaver" , "Equipment, clothing" , "Apparatus" .)
