Island linked by bridge to mainland transformed Senegal close to Saly (8)
I believe the answer is:
anglesey
'island' is the definition.
(I've seen this before)
'transformed senegal close to saly' is the wordplay.
'transformed' indicates anagramming the letters.
'close to' indicates one should take the final letters (the close of something is the end).
The last letter of 'saly' is 'y'.
'senegal' anagrammed gives 'anglese'.
'anglese'+'y'='ANGLESEY'
'linked by bridge to mainland' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for anglesey that I've seen before include "Island off NW tip of Wales" , "Island off N.Wales" , "Welsh county" , "British island known locally as Ynys Mon" , "Welsh island" .)
