Note from British girl (5)
I believe the answer is:
breve
'note' is the definition.
(musical note)
'british girl' is the wordplay.
I cannot really understand how this works, but
'british' could be 'br' (abbreviation for British) and 'br' is found within the answer.
'girl' could be 'eve' and 'eve' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'from' acts as a link.
Can you help me to learn more?
(Other definitions for breve that I've seen before include "(In music) long note" , "Accent - musical note" , "Rarely used musical note" , "Note with the time value of eight crotchets" , "Long note (mus.)" .)
