A soft touch, monk is sold trousers! (4)
I believe the answer is:
kiss
'a soft touch' is the definition.
'kiss' can be an answer for 'touch' (kiss is a kind of touch). I'm not certain of the 'a soft' bit.
'monk is sold trousers' is the wordplay.
'trousers' says the answer is hidden in the clue (trouser can mean to steal or take).
'KISS' can be found hidden inside 'monk is sold'.
Can you help me to learn more?
(Other definitions for kiss that I've seen before include "Smooch" , "Touch lightly - a sign of affection" , "drop of wax" , "x (that may be French)" , "lightness of touch?" .)
