Profession that calls for men with high qualifications (8)
I believe the answer is:
aviation
'profession that calls for men with high qualifications' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
This is all the clue.
Can you help me to learn more?
(Other definitions for aviation that I've seen before include "The business of flying aircraft" , "Job; date" , "The business of airlines" , "The practice or science of flying aircraft" , "Mechanical flight" .)
