Female article carried by aeroplane (5)
I believe the answer is:
janet
'female' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see an association between them that I don't see?
'article carried by aeroplane' is the wordplay.
'article' becomes 'an' (indefinite article).
'carried by' indicates putting letters inside.
'aeroplane' becomes 'jet' (jet is a kind of aeroplane).
'an' going inside 'jet' is 'JANET'.
Can you help me to learn more?
(Other definitions for janet that I've seen before include "academic alliance?" , "Female name" , "Woman" .)
