Play with English pebbles on the beach (7)
I believe the answer is:
Here is my best explanation:
'pebbles on the beach' is the definition.
'play with english' is the wordplay.
'play with' indicates anagramming the letters (I've seen 'plays with' mean this (I've seen this in other clues)).
'english' with letters rearranged gives 'SHINGLE'.
