Meaning 'pound', it gets pounded (4)
I believe the answer is:
beat
'meaning pound' is the definition.
'beat' can be an answer for 'pound' (I've seen this before). I'm not sure about the 'meaning' bit.
'it gets pounded' is the wordplay.
I cannot quite see how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found within the answer.
The remaining letters 'bea' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for beat that I've seen before include "Throb; surpass" , "Rhythmic music unit" , "club" , "Musical rhythm" , "Rhythmic musical unit" .)
