To shoot duck somewhere near Trinidad (6)
I believe the answer is:
tobago
'somewhere near trinidad' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'to shoot duck' is the wordplay.
'shoot' becomes 'bag' (I've seen this in other clues).
'duck' becomes 'o' (resembles zero - 'duck' in cricket).
'to'+'bag'+'o'='TOBAGO'
Can you help me to learn more?
(Other definitions for tobago that I've seen before include "Island in West Indies" , "Trinidad companion island" , "Trinidad's smaller partner island" , "Island paired with Trinidad" , "Island near Trinidad" .)
