Lady upset by North American singer (5)
I believe the answer is:
dylan
'american singer' is the definition.
'dylan' can be an answer for 'singer' (I've seen this before). I'm unsure of the 'american' bit.
'lady upset by north' is the wordplay.
'upset by' is an anagram indicator.
'north' becomes 'N' (abbreviation).
'lady' with letters rearranged gives 'dyla'.
'dyla'+'n'='DYLAN'
Can you help me to learn more?
(Other definitions for dylan that I've seen before include "Bob (singer) - Thomas (author)" , "Popular musician" , "Bob --, Nobel prize winner" , "Great Welsh poet . . . . . Thomas" , "and 19: Welsh poet" .)
