Mean lass confused one taking orders (8)
I believe the answer is:
salesman
'one taking orders' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'mean lass confused' is the wordplay.
'confused' is an anagram indicator.
'mean'+'lass'='meanlass'
'meanlass' with letters rearranged gives 'SALESMAN'.
Can you help me to learn more?
(Other definitions for salesman that I've seen before include "One selling goods" , "Male shop worker" , "He's a vendor" , "Fermented honey drink" , "Slam Sean badly for his selling" .)
