Where to shoot duck in the W. Indies (6)
I believe the answer is:
tobago
'where to shoot duck in the w indies' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'where to shoot duck' is the wordplay.
I cannot really see how this works, but
'to' is within the answer.
'duck' could be 'o' and 'o' is found within the answer.
The remaining letters 'bag' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tobago that I've seen before include "Island in West Indies" , "Trinidad and - (WI)" , "Island paired with Trinidad" , "West Indian island" , "Trinidad companion island" .)
