Initially dead easy reversing vehicle for lorry driver? (4)
I believe the answer is:
derv
'lorry driver?' is the definition.
(derv powers lorries)
'initially dead easy reversing vehicle' is the wordplay.
'initially' says to take the initial letters.
The initial letters of 'dead easy reversing vehicle' is 'DERV'.
'for' acts as a link.
(Other definitions for derv that I've seen before include "Vehicle diesel-oil" , "Fuel for lorries" , "Vehicle fuel oil" , "Lorry fuel" , "Diesel engine fuel oil" .)
