Look to double your money as you laze (4)
I believe the answer is:
loll
'laze' is the definition.
(lolling is a kind of lazing)
'look to double your money as' is the wordplay.
I cannot quite understand how this works, but
'look' could be 'lo' (archaic exclamation meaning 'look!') and 'lo' is located in the answer.
'money' could be 'l' (L can mean 'pounds') and 'l' is present in the answer.
A single letter 'l' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'you' acts as a link.
Can you help me to learn more?
(Other definitions for loll that I've seen before include "Drop" , "Lean back in lazy and relaxed manner" , "Sprawl lazily" , "Lie lazily" , "Hang loosely; sit lazily" .)
