Lord's match? (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
peer
This clue is a double definition.
'lord's' is the first definition.
(I've seen this before)
'match?' is the second definition.
('peer' can be a synonym of 'match')
(Other definitions for peer that I've seen before include "Look closely at lord" , "role in Iolanthe" , "Look closely at titled man?" , "Lord of the realm" , "unelected politician" .)
