A blast radius poorly framed by an article (9)
I believe the answer is:
thrilling
'a blast radius poorly framed by an article' is the definition.
I can't judge whether this definition defines the answer.
'radius poorly framed by an article' is the wordplay.
'radius' becomes 'r' (abbreviation in geometry).
'poorly' becomes 'ill' (synonyms).
'framed by' indicates putting letters inside.
'an article' becomes 'thing' (both can mean an object).
'r'+'ill'='rill'
'rill' put into 'thing' is 'THRILLING'.
Can you help me to learn more?
(Other definitions for thrilling that I've seen before include "Gripping" , "Hair-raising" , "Extremely exciting" , "Sensational" , "Causing pleasurable excitement" .)
