Made a pile (6)
I believe the answer is:
napped
'made a pile' is the definition.
The answer and definition can be both related to bodily activities as well as being past participle verbs.
Perhaps there's a link between them I don't understand?
'pile' is the wordplay.
I cannot really understand how this works, but
'pile' could be 'nap' (both can refer to the surface of a fabric) and 'nap' is found within the answer.
The remaining letters 'ped' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for napped that I've seen before include "Had a doze" , "Slept only lightly" , "Slept for a short while" , "apparently hiding in spieler perversely" , "showing result of hair-raising experience" .)
