Instruction for pilot's punishment (9)
I believe the answer is:
grounding
This clue might be a double definition.
'instruction' is the first definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'pilot's punishment' is the second definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe there's an association between them I don't understand?
'for' acts as a link.
Can you help me to learn more?
(Other definitions for grounding that I've seen before include "Rudimentary knowledge" , "may preclude 19 [FLIGHT]" , "hampering progress of high flier?" , "Foundation of basic knowledge" , "keeping home" .)
