Vocalise quietly, attracting husband’s disapproving grunt (5)
I believe the answer is:
humph
'vocalise quietly attracting husband's disapproving grunt' is the definition.
I can't tell whether this definition defines the answer.
'vocalise quietly attracting husband's' is the wordplay.
'vocalise quietly' becomes 'hump' (I can't justify this - if you can you should give a lot more credence to this answer).
'attracting' says to put letters next to each other.
'husband' becomes 'h' (abbreviation).
'hump'+'h'='HUMPH'
Can you help me to learn more?
(Other definitions for humph that I've seen before include "Clueless chairman" , "annoyed interjection" .)
