Condition to be rejected in kitchen cabinet? (4)
I believe the answer is:
acne
'condition' is the definition.
(acne is a kind of condition)
'rejected in kitchen cabinet?' is the wordplay.
'rejected' says the letters should be written backwards.
'in' indicates the answer is hidden within the clue.
'enca' can be found hidden inside 'kitchen cabinet'.
'enca' in reverse letter order is 'ACNE'.
'to be' is the link.
(Other definitions for acne that I've seen before include "Skin disorder" , "Cane for the teenager?" , "Skin problem, mainly of teenagers" , "Skin affliction" , "sort of disease" .)
