Employed elderly initially in Bucks? (4)
I believe the answer is:
used
'employed' is the definition.
('use' can be a synonym of 'employ')
'elderly initially in bucks?' is the wordplay.
'initially' says to take the initial letters.
'in' means one lot of letters goes inside another.
'bucks?' becomes 'usd' (I can't explain this - if you can you should give a lot more credence to this answer).
The initial letter of 'elderly' is 'e'.
'e' going into 'usd' is 'USED'.
Can you help me to learn more?
(Other definitions for used that I've seen before include "Second-hand; consumed" , "Brought into service" , "Availed oneself of" , "Worn" , "exhausted" .)
