Has been running round again on the beach (6)
I believe the answer is:
ashore
'on the beach' is the definition.
(I've seen this before)
'has been running round again' is the wordplay.
I cannot really understand how this works, but
an anagram of 'has' is 'ash' which is located in the answer.
'round' could be 'o' (round can mean a round object) and 'o' is found in the answer.
'again' could be 're' (prefix meaning 'again') and 're' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ashore that I've seen before include "Returned to land" , "Hoarse (anag)" , "Beached" , "Off the boat" , "on the coast" .)
