Hate to mention I'm somewhere in the Caribbean (5)
I believe the answer is:
haiti
'caribbean' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'hate to mention i'm somewhere in the' is the wordplay.
I cannot really understand how this works, but
'i'm' could be 'i' (I've seen this in other clues) and 'i' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
The remaining letters 'hai' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for haiti that I've seen before include "West Indies republic" , "Country in W Indies, capital Port-au-Prince" , "Republic sharing WI isle" , "West Indies country, capital Port-au-Prince" , "West Indian country, capital Port-au-Prince" .)
