Stamps trams quietly (6)
I believe the answer is:
tramps
'stamps trams' is the definition.
The answer and definition can be both to do with motion as well as being verbs in their -s form.
Perhaps there's an association between them I don't understand?
'quietly' is the wordplay.
I cannot really understand how this works, but
'quietly' could be 'p' (p for piano and quiet) and 'p' is located in the answer.
The remaining letters 'trams' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tramps that I've seen before include "Walks heavily with vagrants" , "Journeys wearily" , "Walks heavily like hoboes" , "Become hard or solid" , "Stumps" .)
