Absurd tasteless clothing starts to cause ridicule (10)
I believe the answer is:
incredible
'absurd' is the definition.
(thesaurus)
'tasteless clothing starts to cause ridicule' is the wordplay.
'tasteless' becomes 'inedible' (I can't justify this - if you can you should believe this answer much more).
'clothing' is an insertion indicator (some letters cover up or clothe others).
'starts to' says to take the initial letters.
The initial letters of 'cause ridicule' is 'cr'.
'inedible' going around 'cr' is 'INCREDIBLE'.
Can you help me to learn more?
(Other definitions for incredible that I've seen before include "Beyond belief" , "Fantastic" , "Unbelievable" , "Impossible to believe" .)
