Draw back from a bit of gardening (4)
I believe the answer is:
drag
'draw' is the definition.
(dragging is a kind of drawing)
'back from a bit of gardening' is the wordplay.
'back from' becomes 'dr' (I am not sure about this - if you are sure you should believe this answer much more).
'bit of' suggests taking the first letters.
The first letter of 'gardening' is 'g'.
'dr'+'a'+'g'='DRAG'
Can you help me to learn more?
(Other definitions for drag that I've seen before include "Pantomime dame's get-up" , "woman's attire" , "Pull - dredge - transvestite habit" , "Women's clothes worn by a man - pull" , "Move with difficulty" .)
