Very silly senior account (7)
I believe the answer is:
version
'account' is the definition.
(I know that version is a type of interpretation)
'very silly senior' is the wordplay.
'very' becomes 'v' (abbreviation).
'silly' indicates anagramming the letters.
'senior' is an anagram of 'ersion'.
'v'+'ersion'='VERSION'
(Other definitions for version that I've seen before include "Description from a certain point of view" , "Sort" , "Particular form (of something)" , "Translation - personal account" , "Model" .)
