Voucher given to fellow (5)
I believe the answer is:
token
'voucher' is the definition.
(I've seen this before)
'given to fellow' is the wordplay.
'given' says to put letters next to each other.
'fellow' becomes 'ken' (I can't explain this - if you can you should believe this answer much more).
'to'+'ken' is 'TOKEN'.
Can you help me to learn more?
(Other definitions for token that I've seen before include "Symbolic; voucher" , "signal" , "Emblem" , "Badge; voucher" , "Indication, symbol or voucher" .)
