She put together three articles (6)
I believe the answer is:
anthea
'she' is the definition.
(I've seen this before)
'put together three articles' is the wordplay.
'three articles' means three replacements for 'article'.
'put together' means one lot of letters go next to another.
'article' becomes 'an' (English indefinite article).
'article' becomes 'the' (the definite article in English).
'article' becomes 'a' (the indefinite article in English).
'an' put next to 'the' is 'anthe'.
'anthe'+'a'='ANTHEA'
(Other definitions for anthea that I've seen before include "Woman" , "Girl" , "Female" .)
