Quote from additional court (7)
I believe the answer is:
extract
'quote' is the definition.
(thesaurus)
'additional court' is the wordplay.
'additional' becomes 'extra' (I've seen this before).
'court' becomes 'ct' (abbreviation used in road names).
'extra'+'ct'='EXTRACT'
'from' acts as a link.
(Other definitions for extract that I've seen before include "Pluck out" , "Derive, distil" , "bit" , "Short passage from a longer work" , "Pull or take out - maybe a tooth" .)
