Fraternise at the centre and learn regularly in order to gain enlightenment, maybe. (7)
I believe the answer is:
lantern
'order to gain enlightenment maybe' is the definition.
I can't judge whether this defines the answer.
'fraternise at the centre and learn regularly' is the wordplay.
'at the centre' means to look at the middle letters.
'and' says to put letters next to each other.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The central letters of 'fraternise' are 'tern'.
The alternating letters of 'learn' are 'lan'.
'tern' put after 'lan' is 'LANTERN'.
'in' is the link.
Can you help me to learn more?
(Other definitions for lantern that I've seen before include "Top of lighthouse" , "Type of lamp" , "Light in a protective casing" , "Portable lamp case" , "Leading light" .)
