Curious airs displayed by chosen member of ancient ethnic group (9)
I believe the answer is:
israelite
'member of ancient ethnic group' is the definition.
The definition suggests a singular noun which matches the answer.
'curious airs displayed by chosen' is the wordplay.
'curious' indicates an anagram.
'displayed by' says to put letters next to each other.
'chosen' becomes 'elite' (I've seen this before).
'airs' with letters rearranged gives 'isra'.
'isra'+'elite'='ISRAELITE'
Can you help me to learn more?
(Other definitions for israelite that I've seen before include "Jew" , "For example, Nathanael" , "one of the chosen?" , "Ancient Hebrew" , "Tribesman" .)
