Initially nothing found inside broken article — blow it! (8)
I believe the answer is:
clarinet
'initially nothing found inside broken article blow it' is the definition.
I can't tell whether this defines the answer.
'initially nothing found inside broken article' is the wordplay.
'initially' suggests taking the first letters.
'found inside' is an insertion indicator.
'broken' indicates anagramming the letters.
The initial letter of 'nothing' is 'n'.
'article' with letters rearranged gives 'clariet'.
'n' placed within 'clariet' is 'CLARINET'.
Can you help me to learn more?
(Other definitions for clarinet that I've seen before include "Find an instrument in claret" , "Source of music" , "Woodwind instrument played by Artie Shaw and Benny Goodman" , "Single-reed straight-tubed instrument" , "member of orchestra" .)
