Oddly hoped city swayed two artistic panels (7)
I believe the answer is:
diptych
'oddly hoped city swayed two artistic panels' is the definition.
I can't tell whether this defines the answer.
'oddly hoped city swayed' is the wordplay.
'oddly' means one should take alternating letters (letters in the odd-numbered positions are used).
'swayed' indicates anagramming the letters (I've seen 'swaying' mean this (letters swaying or moving around)).
The alternate letters of 'hoped' are 'hpd'.
'hpd'+'city'='hpdcity'
'hpdcity' is an anagram of 'DIPTYCH'.
Can you help me to learn more?
(Other definitions for diptych that I've seen before include "Two-part painting" , "Picture with two panels" , "Pair of paintings on two hinged panels" , "Painting on dual surface, that folds" , "Painting with two hinged panels" .)
