Student in strange rite becomes illuminated again (5)
I believe the answer is:
relit
'illuminated again' is the definition.
(I've seen this before)
'student in strange rite' is the wordplay.
'student' becomes 'l' (learner, as in L-plates for learner drivers).
'in' indicates putting letters inside.
'strange' indicates an anagram.
'rite' anagrammed gives 'reit'.
'l' placed within 'reit' is 'RELIT'.
'becomes' acts as a link.
(Other definitions for relit that I've seen before include "in flames again" , "got going again" , "Again fired" , "Illuminated again" , "Tiler (anag.)" .)
