Husband, father, born great, overthrown: no sense in this (9)
I believe the answer is:
gibberish
'no sense in this' is the definition.
The definition suggests a singular noun which matches the answer.
'husband father born great overthrown' is the wordplay.
'husband' becomes 'h'.
'father' becomes 'sire' ('sire' can be a synonym of 'father').
'born' becomes 'b'.
'great' becomes 'big' ('big' can be a synonym of 'great'**).
'overthrown' says the letters should be written backwards.
'h'+'sire'+'b'+'big'='hsirebbig'
'hsirebbig' reversed gives 'GIBBERISH'.
Can you help me to learn more?
(Other definitions for gibberish that I've seen before include "Meaningless speech" , "Rubbish" , "moonshine" , "Meaningless talk" , "Tosh" .)
