Brother performing with church beginning to improvise organ passages (7)
I believe the answer is:
bronchi
'organ passages' is the definition.
The answer and definition can be both body parts as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'brother performing with church beginning to improvise' is the wordplay.
'brother' becomes 'br' (abbreviation in titles of monks).
'performing' becomes 'on' (as in being on stage).
'with' is a charade indicator (letters next to each other).
'church' becomes 'ch' (common abbreviation).
'beginning to' says to take the initial letters.
The first letter of 'improvise' is 'i'.
'br'+'on'+'ch'+'i'='BRONCHI'
Can you help me to learn more?
(Other definitions for bronchi that I've seen before include "pipes" , "In airways" , "breathers" , "airy spaces" , "Tubes" .)
