Spades also remove the stones from play area (7)
I believe the answer is:
sandpit
'play area' is the definition.
(I've seen this before)
'spades also remove' is the wordplay.
'spades' becomes 's' (abbreviation in card games).
'also' becomes 'and' (both can mean in addition).
'remove' becomes 'pit' (pitting is a kind of removing).
's'+'and'+'pit'='SANDPIT'
'the stones from' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for sandpit that I've seen before include "Play area for small children" , "Play area; quarry" , "Playground feature" , "place where youngsters can play" , "children may play here" .)
