untruthfulness
Tendency toward falsehood
Untruthfulness is the quality of not telling the truth—a tendency toward dishonesty or deception.
The word emphasizes ongoing character rather than a single instance: His untruthfulness made it impossible to trust anything he said.
It carries a formal, almost clinical tone compared to simpler words like lying or dishonesty.
