Drown one out, as you'd expect (2,6)
I believe the answer is:
no wonder
'you'd expect' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'drown one out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'drown'+'one'='drownone'
'drownone' is an anagram of 'NO WONDER'.
'as' is the link.
Can you help me to learn more?
(Other definitions for no wonder that I've seen before include "hardly unforeseen" , "it isn't surprising" , "hardly unexpected" .)
