They gather to see gold finish on concert centre (8)
I believe the answer is:
audience
'they gather' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'see gold finish on concert centre' is the wordplay.
'see gold' becomes 'Au' (Au is the chemical symbol for gold).
'finish' becomes 'die' ().
'on' means one lot of letters go next to another.
'centre' says to take the centre.
The central letters of 'concert' are 'nce'.
'au'+'die'+'nce'='AUDIENCE'
'to' is the link.
Can you help me to learn more?
(Other definitions for audience that I've seen before include "Formal interview; those at e.g. play" , "House" , "Assembled spectators or listeners" , "Spectators - interview" , "Assembly gathered to watch, say, a play" .)
