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'm not certain of the 'of camping?' bit.
'purpose of camping?' is the wordplay.
'purpose of' becomes 'in' (I can't explain this - if you can you should believe this answer much more).
'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" .)
