Ornamental pattern, say, from part of classical Attic era (7)
I believe the answer is:
lattice
'ornamental pattern' is the definition.
(I know that lattice is a ornamental pattern)
'of classical attic era' is the wordplay.
'of' indicates a hidden word.
'LATTICE' is hidden within 'classical attic era'.
'say from part' is the 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 lattice that I've seen before include "Window with criss-cross strips of lead" , "Network of crossed bars" , "Network of crossed laths" , "Framework for window" , "Sort of window" .)
