Walk, asleep and moving (9)
I believe the answer is:
esplanade
'walk' is the definition.
(I know that esplanade is a type of walk)
'asleep and moving' is the wordplay.
'moving' is an anagram indicator (letters are moved around).
'asleep'+'and'='asleepand'
'asleepand' with letters rearranged gives 'ESPLANADE'.
(Other definitions for esplanade that I've seen before include "place for a stroll" , "Long stretch of open seafront for walking or driving" , "Paved area at seaside resort" , "Open, level space for walks or drives" , "Sea-front drive" .)
