She may translate an article for Gert (5)
I believe the answer is:
greta
'she' is the definition.
'translate an article for gert' is the wordplay.
'translate' is an anagram indicator (translate can mean to transform).
'an article' becomes 'a' (the indefinite article in English).
'for' is a charade indicator (letters next to each other).
'a'+'gert'='agert'
'agert' anagrammed gives 'GRETA'.
'may' is the link.
(Other definitions for greta that I've seen before include "- Garbo, Swed. actress" , "- Garbo, Swedish actress" , "Woman" , "Female" , ".....Garbo, who wanted to be alone" .)
