Company with high-flying employees? (7)
I believe the answer is:
airline
'company with high-flying employees?' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'flying employees?' is the wordplay.
'flying' becomes 'air' (similar in meaning).
'employees?' becomes 'line' (I am not sure about this - if you are sure you should believe this answer much more).
'air'+'line'='AIRLINE'
Can you help me to learn more?
(Other definitions for airline that I've seen before include "It creates inflation" , "company supplying transport" , "Company operating aeroplanes" , "carrier" , "Transport organisation" .)
