Play area with family lounge (7)
I believe the answer is:
recline
'lounge' is the definition.
(both can mean to laze around)
'play area with family' is the wordplay.
'play area' becomes 'rec' (short for recreation ground).
'with' means one lot of letters go next to another.
'family' becomes 'line' (one's lineage).
'rec'+'line'='RECLINE'
(Other definitions for recline that I've seen before include "Lie on one's back" , "Assume horizontal or leaning position as for rest" , "Lie in a comfortable position" , "Adopt horizontal or leaning position" , "Lounge" .)
