College intrudes on UK tenant developing Massachusetts resort (9)
I believe the answer is:
nantucket
'resort' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see an association between them that I can't see?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for nantucket that I've seen before include "US island" , "Island resort off Cape Cod" , "Massachusetts island port from which the Pequod sailed (Moby Dick)" , "American island" , "US resort" .)
