The purpose of camping? (6)
I believe the answer is:
intent
'the purpose' is the definition.
('intent' can be a synonym of 'purpose')
'camping?' is the wordplay.
I cannot really understand how this works, but
'camping?' could be 'tent' (I've seen this in other clues) and 'tent' is found in the answer.
The remaining letters 'in' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for intent that I've seen before include "'Engrossed, absorbed (6)'" , "Firm - plan - steadfast - purpose" , "Eager" , "Meaning -- determined" , "Purpose, design" .)
