Rogue punched by husband in a state (4)
I believe the answer is:
chad
'a state' is the definition.
(I know that Chad is a African country)
'rogue punched by husband' is the wordplay.
'rogue' becomes 'cad' (I've seen this in another clue).
'punched by' is an insertion indicator (some letters punch a hole in others).
'husband' becomes 'h' (abbreviation).
'cad' going around 'h' is 'CHAD'.
'in' acts as a link.
(Other definitions for chad that I've seen before include "Fish" , "N central African country" , "Punched paper; African nation" , "Country - which got Bush elected in Florida?" , "Small piece that's removed when a hole is punched, in a card say" .)
