Loose shingle from a part of these shores (7)
I believe the answer is:
english
'from a part of these shores' is the definition.
(from England, part of the UK)
'loose shingle' is the wordplay.
'loose' indicates an anagram (letters are loosened from their original positions).
'shingle' anagrammed gives 'ENGLISH'.
(Other definitions for english that I've seen before include "Common language" , "to write these answers in?" , "The Queen's language?" , "A country condiment?" , "Widely-spoken language" .)
