Jumble sale man jumping with lice (11)
I believe the answer is:
miscellanea
'jumble' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'sale man jumping with lice' is the wordplay.
'jumping with' indicates anagramming the letters.
'sale'+'man'='saleman'
'saleman' anagrammed with 'lice' makes 'MISCELLANEA'.
Can you help me to learn more?
(Other definitions for miscellanea that I've seen before include "Disorganized bunch" , "Collection" .)
