From the north-east: new girl (5)
I believe the answer is:
nesta
'new girl' is the definition.
'Nesta' can be an answer for 'girl'. I am not sure about the 'new' bit.
'from the north-east' is the wordplay.
'from' indicates anagramming the letters (from the letters).
'the north' becomes 'N' (abbreviation).
'n'+'east'='neast'
'neast' anagrammed gives 'NESTA'.
Can you help me to learn more?
(Other definitions for nesta that I've seen before include "woman" , "girl" .)
