Position of Lord's okay with member (4,3)
I believe the answer is:
fine leg
'position of lord's' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'okay with member' is the wordplay.
'okay' becomes 'fine' (both are ways of saying 'yes').
'with' means one lot of letters go next to another.
'member' becomes 'leg' (member can mean a limb).
'fine'+'leg'='FINE LEG'
Can you help me to learn more?
(Other definitions for fine leg that I've seen before include "Man in field" , "Fielder behind the wicket" , "Fielding position" .)
