Purpose of camping? (6)
I believe the answer is:
intent
'purpose of camping?' is the definition.
'intent' can be an answer for 'purpose' (synonyms). I am unsure of the 'of camping?' bit.
'purpose of camping?' is the wordplay.
'purpose of' becomes 'in' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'camping?' becomes 'tent' (I've seen this in other clues).
'in'+'tent'='INTENT'
Can you help me to learn more?
(Other definitions for intent that I've seen before include "Meaning -- determined" , "With attention concentrated, bent on" , "Bent on, resolved" , "Bent on, determined to" , "Concentrating on a particular purpose" .)
