So keeps bloke from Genesis at front of record book (9)
I believe the answer is:
thesaurus
'book' is the definition.
(thesaurus is a kind of book)
'so keeps bloke from genesis at front of record' is the wordplay.
I cannot really see how this works, but
'bloke' could be 'he' ('he' refers to a man) and 'he' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for thesaurus that I've seen before include "Book listing synonyms" , "Wordy gathering" , "Word book" , "lists?" , "Wordbook" .)
