Sleeps with piles? (4)
I believe the answer is:
naps
This clue is a double definition.
'sleeps' is the first definition.
(I know this)
'piles?' is the second definition.
(I've seen this in another clue)
'with' is the link.
(Other definitions for naps that I've seen before include "Takes forty winks" , "Span including short sleeps" , "Tips; sleeps" , "Snoozes" .)
