Long for bloke over time (5)
I believe the answer is:
covet
'long for' is the definition.
(I've seen this before)
'bloke over time' is the wordplay.
'bloke' becomes 'cove' (I've seen this in other clues).
'over' says to put letters next to each other.
'time' becomes 't'.
'cove'+'t'='COVET'
(Other definitions for covet that I've seen before include "Envy" , "Long to have (something belonging to another)" , "Crave, long to possess" , "Desire eagerly" , "Want something belonging to another" .)
