One reads everything in report about work-out (8)
I believe the answer is:
bookworm
'one reads everything' is the definition.
I can't judge whether this definition defines the answer.
'report about work-out' is the wordplay.
'report' becomes 'boom' (both can mean a loud noise).
'about' indicates putting letters inside.
'out' indicates an anagram (out can mean wrong or inaccurate).
'work' with letters rearranged gives 'kwor'.
'boom' enclosing 'kwor' is 'BOOKWORM'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for bookworm that I've seen before include "Excessive reader - type of louse" , "Incessant reader" , "Person excessively fond of reading, like earth creature" , "keen student" , "voracious reader" .)
