Whispered about interrupting very young child’s washing (5,4,6)
I believe the answer is:
under ones breath
'whispered' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'about interrupting very young child's washing' is the wordplay.
'about' becomes 're' (regarding).
'interrupting' indicates putting letters inside.
'very young' becomes 'under one' (under one year of age).
'child's washing' becomes 'sbath' (I am not sure about this - if you are sure you should believe this answer much more).
'underone'+'sbath'='underonesbath'
're' placed within 'underonesbath' is 'UNDER ONES BREATH'.
Can you help me to learn more?
(Another definition for under ones breath that I've seen is " quietly".)
