Judge Arizona zone with lively manner (4)
I believe the answer is:
jazz
'lively manner' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'judge arizona zone' is the wordplay.
'judge' becomes 'j' (abbreviation for judge).
'arizona' becomes 'az' (I've seen this in other clues).
'zone' becomes 'z'.
'j'+'az'+'z'='JAZZ'
'with' is the link.
Can you help me to learn more?
(Other definitions for jazz that I've seen before include "eg Trad" , "Popular music from New Orleans" , "Type of music" , "Miles Davis music" , "Music of African-American origin" .)
