Co-write talk about ornamental trellises, for example (11)
I believe the answer is:
latticework
'trellises for example' is the definition.
(I know that treillage is a type of latticework)
'co-write talk about' is the wordplay.
'about' is an anagram indicator.
'co'+'write'+'talk'='cowritetalk'
'cowritetalk' with letters rearranged gives 'LATTICEWORK'.
'ornamental' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for latticework that I've seen before include "grating" , "Criss-crossed arrangement" , "crisscross effect?" , "decorative topping for fence" .)
