Find out about dead becoming bloated (8)
I believe the answer is:
inflated
'bloated' is the definition.
(thesaurus)
'find out about dead' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'about' means one lot of letters goes inside another.
'dead' becomes 'late' (similar in meaning).
'find' with letters rearranged gives 'infd'.
'infd' enclosing 'late' is 'INFLATED'.
'becoming' acts as a link.
(Other definitions for inflated that I've seen before include "Filled with air or gas to distend" , "Extravagant" , "Exaggerated (and liable to 5?)" , "Blown up" , "Bombastic" .)
