Most of literary family is seen around very significant peak (3,5)
I believe the answer is:
ben nevis
'significant peak' is the definition.
'most of literary family is seen around very' is the wordplay.
'most of' means to remove the last letter.
'literary family' becomes 'bennet' (Bennet family from Pride and Prejudice).
'seen around' is an insertion indicator.
'very' becomes 'v' (abbreviation).
'bennet' with its final letter taken away is 'benne'.
'benne'+'is'='benneis'
'benneis' going around 'v' is 'BEN NEVIS'.
(Other definitions for ben nevis that I've seen before include "The highest peak in Scotland" , "top position up North" , "UK's highest mountain" , "Highest spot in Britain" , "Highest UK mountain" .)
