Artist, quiet, extremely lazy in foolhardy way (6)
I believe the answer is:
rashly
'artist quiet extremely lazy in foolhardy way' is the definition.
I can't judge whether this definition defines the answer.
'artist quiet extremely lazy' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'quiet' becomes 'sh' ('sh' is used to tell someone to be quiet).
'extremely' says to hollow out the word (remove centre letters) (only the extremes of the word are used).
'lazy' with its middle removed is 'ly'.
'ra'+'sh'+'ly'='RASHLY'
Can you help me to learn more?
(Other definitions for rashly that I've seen before include "In a hasty and foolhardy manner" , "Recklessly" , "in reckless fashion" , "Without caution" , "Without forethought" .)
