Nuisance, a line editor introduced that holds up column (8)
I believe the answer is:
pedestal
'column' is the definition.
(thesaurus)
'nuisance a line editor introduced' is the wordplay.
'nuisance' becomes 'pest' (I've seen this before).
'line' becomes 'l' (used when specifying particular lines from a poem).
'editor' becomes 'ed' (abbreviation).
'introduced' means one lot of letters goes inside another.
'pest'+'a'+'l'='pestal'
'pestal' placed around 'ed' is 'PEDESTAL'.
'that holds up' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for pedestal that I've seen before include "Stand for statue or basin" , "Base (for statue, etc)" , "Architectural support or base" , "Place for hero" , "Column support, on which one is worshipped" .)
