One pounded with the feet? (4)
I believe the answer is:
beat
'one' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'pounded with the feet?' is the wordplay.
'pounded' becomes 'bat' (I can't explain this - if you can you should give a lot more credence to this answer).
'with' indicates putting letters inside.
'feet?' suggests the final letters (I've seen 'foot' mean this (in a down clue, the bottom letter)).
The last letter of 'the' is 'e'.
'bat' going around 'e' is 'BEAT'.
Can you help me to learn more?
(Other definitions for beat that I've seen before include "Worst - best" , "Musical rhythm" , "club" , "Come out better than in a competition" , "Conquer" .)
