Means it's something to play (10)
I believe the answer is:
instrument
'means' is the definition.
(instrument is a kind of means)
'it's something to play' is the wordplay.
I cannot really understand how this works, but
'play' could be 'strum' (I've seen this before) and 'strum' is located in the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for instrument that I've seen before include "What's needed for 1 [MUSICIAN]" , "Joanna, perhaps" , "legal document" , "Means of precision work (or music-making)" , "Word puzzle" .)
