A book with recipe put off? It's unexpected (6)
I believe the answer is:
abrupt
'unexpected' is the definition.
(thesaurus)
'a book with recipe put off?' is the wordplay.
'book with' becomes 'b' (I am not sure about the 'with' bit.**).
'recipe' becomes 'r' (abbreviation).
'off?' indicates anagramming the letters (I've seen 'off' mean this).
'put' anagrammed gives 'upt'.
'a'+'b'+'r'+'upt'='ABRUPT'
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for abrupt that I've seen before include "Short and rude" , "Sudden, maybe rude" , "Curt and short" , "brisk" , "Terse, curt" .)
