Hint at introduction of absolutely stupid measure (9)
I believe the answer is:
adumbrate
'hint' is the definition.
(adumbrating is a kind of hinting)
'at introduction of absolutely stupid measure' is the wordplay.
I cannot quite understand how this works, but
'at' is within the answer.
'stupid' could be 'dumb' (similar in meaning) and 'dumb' is found within the answer.
'measure' could be 'are' (are is a kind of measure) and 'are' is present in the leftover letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for adumbrate that I've seen before include "sketch" , "Indicate or describe in a general way" , "Give a faint idea of; overshadow" , "Depict in outline" , "Obscure" .)
