Absurdly taken out where the dirty stuff goes (7,6)
I believe the answer is:
laundry basket
'where the dirty stuff goes' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'absurdly taken out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'absurdly'+'taken'='absurdlytaken'
'absurdlytaken' with letters rearranged gives 'LAUNDRY BASKET'.
Can you help me to learn more?
(Other definitions for laundry basket that I've seen before include "Receptacle for dirty linen" , "Container for 10" , "Container for dirty washing" , "Receptacle for dirty clothing" .)
