Demands an unspecified number of stories from reporter (7)
I believe the answer is:
entails
This could be a double definition.
'demands an unspecified number' is the first definition.
The definition and answer can be both to do with fundamental existence as well as being verbs in their -s form.
Maybe there's an association between them I don't understand?
'stories from reporter' is the second definition.
Although both the answer and definition are plural nouns, I can't understand how they can define each other.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for entails that I've seen before include "Involves, makes necessary" , "limits of will" , "Necessitates" , "Has as a logical consequence" , "Has as a direct consequence" .)
