Point learnt about being everlasting (7)
I believe the answer is:
eternal
'being everlasting' is the definition.
('eternal' can be a synonym of 'everlasting')
'point learnt about' is the wordplay.
'point' becomes 'e' (compass point).
'about' indicates an anagram.
'learnt' anagrammed gives 'ternal'.
'e'+'ternal'='ETERNAL'
(Other definitions for eternal that I've seen before include "Infinite - endless" , "abiding" , "what should be unchangeable" , "Undying" , "Everlasting, not affected by time" .)
