Insignificant view about a learner (6)
I believe the answer is:
slight
'insignificant' is the definition.
(thesaurus)
'view about a learner' is the wordplay.
'view' becomes 'sight' (synonyms).
'about' is an insertion indicator.
'a learner' becomes 'l' (as in a learner driver with L-plates on their car).
'sight' placed around 'l' is 'SLIGHT'.
(Other definitions for slight that I've seen before include "Insubstantial; insult" , "Put down" , "Affront of delicate sort" , "slap in the face" , "Snub - not much!" .)
