Confront eccentric king, perhaps (4,4)
I believe the answer is:
face card
'king perhaps' is the definition.
(king is a kind of face card)
'confront eccentric' is the wordplay.
'confront' becomes 'face' ('face' can be a synonym of 'confront').
'eccentric' becomes 'card' (I've seen this before).
'face'+'card'='FACE-CARD'
(Other definitions for face card that I've seen before include "queen, perhaps" , "King, queen or jack" , "Knave, perhaps" , "Maybe knave" , "Jack for instance" .)
