Spanish article by boy or girl (5)
I believe the answer is:
ellen
'girl' is the definition.
'spanish article by boy' is the wordplay.
'spanish article' becomes 'el' (the definite article 'the' in Spanish).
'by' is a charade indicator (letters next to each other).
'boy' becomes 'len' (boy's name).
'el'+'len'='ELLEN'
'or' is the link.
(Other definitions for ellen that I've seen before include "- Terry, Eng. actress" , "Terry perhaps" , "It could be Terry" , "Girl" , "Girl's name" .)
