Type of jazz covers popular with brides, essentially, in Caribbean island (8)
I believe the answer is:
trinidad
'caribbean island' is the definition.
(I've seen this before)
'type of jazz covers popular with brides essentially' is the wordplay.
'type of jazz' becomes 'trad' (I've seen this before).
'covers' is an insertion indicator.
'popular with' becomes 'in' (I can't explain this - if you can you should give a lot more credence to this answer).
'essentially' means to look at the middle letters.
The centre of 'brides' is 'id'.
'in'+'id'='inid'
'trad' placed around 'inid' is 'TRINIDAD'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for trinidad that I've seen before include "... [WI ISLAND]" , "Island linked to Tobago" , "W. I. island" , "West Indies island" , "Caribbean island" .)
