Where camper might be if female's abandoned on purpose (9)
I believe the answer is:
intention
'purpose' is the definition.
(I know that purpose can be written as intention)
'where camper might be if female's abandoned on' is the wordplay.
'where camper might be' becomes 'in tent' (someone might camp in a tent).
'female' becomes 'f' (abbreviation).
'abandoned' suggests deleting specific letters.
'if' with 'f' taken away is 'i'.
'intent'+'i'+'on'='INTENTION'
(Other definitions for intention that I've seen before include "Plan, purpose" , "goal" , "Aim, plan" , "Design" , "Aim, purpose" .)
