A hat to start queuing for? (5)
I believe the answer is:
toque
'a hat' is the definition.
(toque is a kind of hat)
'to start queuing for?' is the wordplay.
'start' suggests taking the first letters.
'for?' becomes 'ue' (I can't justify this - if you can you should believe this answer much more).
The initial letter of 'queuing' is 'q'.
'to'+'q'+'ue'='TOQUE'
Can you help me to learn more?
(Other definitions for toque that I've seen before include "Small brimless hat" , "Close-fitting hat" , "Sri Lankan monkey" , "Woman's round, brimless hat" , "Turban" .)
