Playing for fun, a pal you’re texting (7)
I believe the answer is:
amateur
'playing for fun' is the definition.
(as opposed to professional)
'a pal you're texting' is the wordplay.
'pal' becomes 'mate' (both can mean a friend).
'you're texting' becomes 'ur' (informal spelling of 'you're' eg in text messages).
'a'+'mate'+'ur'='AMATEUR'
(Other definitions for amateur that I've seen before include "Dabbler" , "Lay person" , "Not pro" , "Receiving no money" , "Unpaid or unskilled" .)
