Book that can make an idiot cry? (10)
I believe the answer is:
dictionary
'book' is the definition.
(I know that dictionary is a type of book)
'can make an idiot cry?' is the wordplay.
'can make' is an anagram indicator (I've seen this in other clues).
'an'+'idiot'+'cry'='anidiotcry'
'anidiotcry' is an anagram of 'DICTIONARY'.
'that' acts as a link.
(Other definitions for dictionary that I've seen before include "Lexicon" , "glossary" , "Brewer's creation, say" , "Ordered book" , "reference work" .)
