What is the definition of 'fool' in Theravada Buddhist text?

The Lakkhana Sutta says, > Endowed with three things, monks, a fool can be known as a fool. What three? By bodily misconduct, by verbal misconduct, by mental misconduct. Endowed with these three things, monks, a fool can known as a fool. But everyone has bodily misconduct, verbal misconduct and mental misconduct (I say that because we make mistakes from time to time, at least to a certain extent). So how to differentiate between a fool's (bodily, verbal and mental) misconduct, compared to a wise person's (bodily, verbal and mental) misconduct?
