Student's particular form of energy enveloping church (7)
I believe the answer is:
scholar
'student's' is the definition.
(scholar is a kind of student)
'energy enveloping church' is the wordplay.
'energy' becomes 'solar' (solar energy is a kind of energy).
'enveloping' means one lot of letters goes inside another.
'church' becomes 'ch' (abbreviation on maps etc).
'solar' placed around 'ch' is 'SCHOLAR'.
'particular form of' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for scholar that I've seen before include "Student or learned person" , "Academic, schoolboy" , "Pupil - erudite person" , "Distinguished academic" , "Learned (or learning) one" .)
