A musical little number from Locarno, possibly (5)
I believe the answer is:
carol
'a musical' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'little number from locarno possibly' is the wordplay.
'little number' becomes 'no' (abbreviated form of 'number').
'from' indicates named letters should be taken away.
'possibly' indicates anagramming the letters.
'locarno' with 'no' taken out is 'locar'.
'locar' with letters rearranged gives 'CAROL'.
Can you help me to learn more?
(Other definitions for carol that I've seen before include "A traditional Christmas song or hymn" , "Joyful hymn" , "See 1" , "Canticle" , "Religious song - girl's name" .)
