She wants a thousand different (6)
I believe the answer is:
mother
'she' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'a thousand different' is the wordplay.
'a thousand' becomes 'm' (Roman numeral for a thousand).
'different' becomes 'other' (similar in meaning).
'm'+'other'='MOTHER'
'wants' acts as a link.
Can you help me to learn more?
(Other definitions for mother that I've seen before include "Nature so-called" , "Fuss over" , "Female parent" , "Dam" , "Mum" .)
