Clue: Hint of a sort? Reduced to guessing (10)
Answer: SUGGESTION
Explanation: Definition: Hint
***(to guessing)** [anag:*reduced*] 
 
 
*I'm assuming that "reduced" is the anagram indicator, but I don't like it. Even in its culinary meaning, "reduced" means "lessened" not "mixed". The clue could have been simply something like "Hint? Resort to guessing."
