Issues about extremely short book (8)
I believe the answer is:
proverbs
'book' is the definition.
(I've seen this before)
'issues about extremely short' is the wordplay.
'issues' becomes 'probs' (I can't explain this - if you can you should believe this answer much more).
'about' indicates putting letters inside.
'extremely short' becomes 'ver' (I've seen this in other clues).
'probs' enclosing 'ver' is 'PROVERBS'.
Can you help me to learn more?
(Other definitions for proverbs that I've seen before include "Truthful expressions" , "Book of the Bible" , "Old Testament book ascribed to Solomon, or well-known sayings" , "More than one saw" , "Adages, saws" .)
