Trimmed and arranged in twos, we're told (5)
I believe the answer is:
pared
'trimmed' is the definition.
('pare' can be a synonym of 'trim')
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for pared that I've seen before include "Cut bit by bit" , "Did prune" , "Whittled as with pencil" , "Trimmed like pencil." , "Of a fruit, peeled" .)
