One instrumental in taking up a collection? (5)
I believe the answer is:
cello
'one instrumental in' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'up a collection?' is the wordplay.
'CELLO' is hidden backwards within the letters.
But, I am uncertain how the hidden word is indicated.
'taking' acts as a link.
Can you help me to learn more?
(Other definitions for cello that I've seen before include "Viola's bigger brother?" , "has strings attached" , "Bass stringed instrument" , "String quartet instrument" , "It's bigger than a viola, but smaller than a double bass" .)
