Trimmed, again, in the home (5)
I believe the answer is:
pared
'trimmed' is the definition.
('pare' can be a synonym of 'trim')
'again in the home' is the wordplay.
'again' becomes 're'.
'in' means one lot of letters goes inside another.
'the home' becomes 'pad' (I've seen this before).
're' put inside 'pad' is 'PARED'.
(Other definitions for pared that I've seen before include "Peeled the outer surface" , "Did prune" , "Cut bit by bit" , "Trimmed like pencil." , "Of a fruit, peeled" .)
