Go in the meadow at five with earl (5)
I believe the answer is:
leave
'go' is the definition.
(go can mean to depart or leave)
'meadow at five with earl' is the wordplay.
'meadow' becomes 'lea' (a lea is a grassy area).
'at' says to put letters next to each other.
'five' becomes 'V' (Roman numeral).
'with' says to put letters next to each other.
'earl' becomes 'e'.
'lea'+'v'+'e'='LEAVE'
'in the' is the link.
(Other definitions for leave that I've seen before include "Furlough" , "Quit; permission" , "Go - on holidays?" , "ditch" , "Permission - time off" .)
