Where a dancer may use an alias, on the quiet? (6)
I believe the answer is:
palais
'where a dancer' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'use an alias on the quiet?' is the wordplay.
'use' is an anagram indicator.
'on' means one lot of letters goes inside another (as in clothing 'on' a person).
'the quiet?' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'alias' is an anagram of 'alais'.
'alais' enclosing 'p' is 'PALAIS'.
'may' is the link.
Can you help me to learn more?
(Another definition for palais that I've seen is " dance-hall".)
