As local inhabitant, study one form of Buddhism (7)
I believe the answer is:
denizen
'as local inhabitant' is the definition.
'denizen' can be an answer for 'inhabitant' (synonyms). I am unsure of the 'as local' bit.
'study one form of buddhism' is the wordplay.
'study' becomes 'den' (term for a study or office).
'one' becomes 'i' (Roman numeral).
'form of buddhism' becomes 'zen' (Zen is a school of Buddhism).
'den'+'i'+'zen'='DENIZEN'
Can you help me to learn more?
(Other definitions for denizen that I've seen before include "Resident" , "Dweller" , "Person in foreign country enjoying rights of natives" , "Inhabitant, occupant" , "Enid Zen (anag) - inhabitant of a particular place" .)
