Coarse gravel found in English ground (7)
I believe the answer is:
shingle
'coarse gravel' is the definition.
(I've seen this before)
'english ground' is the wordplay.
'ground' indicates an anagram (grind the letters ).
'english' anagrammed gives 'SHINGLE'.
'found in' is the link.
(Other definitions for shingle that I've seen before include "A mass of seashore pebbles" , "Bob" , "Here one comes close to the main" , "may be lying on the beach" , "Gravelly composition" .)
