A few lines from the Home Counties that may stand (6)
I believe the answer is:
sestet
'a few lines' is the definition.
(the last six lines of a sonnet)
'home counties that may stand' is the wordplay.
'home counties' becomes 'SE' (the Home Counties are in the South East of England).
'that may stand' becomes 'stet' (printing instruction to let a piece of text stand).
'se'+'stet'='SESTET'
'from the' acts as a link.
(Other definitions for sestet that I've seen before include "Set of six performers" , "musical ensemble" , "Six together" , "Tsetse (anag.)" , "Group of six" .)
