Beer’s replaced with aqua, Islamic style (9)
I believe the answer is:
arabesque
'islamic style' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'beer's replaced with aqua' is the wordplay.
'replaced with' indicates an anagram.
'beers' with its letters mixed up with 'aqua' makes 'ARABESQUE'.
Can you help me to learn more?
(Other definitions for arabesque that I've seen before include "Ballet position with one leg raised" , "posture only half-supported" , "A square be a ballet movement?" , "part of ballet" , "Posture in ballet" .)
