PRONUNCIATION:

(men-DAS-i-tee) 

MEANING:

noun:
1. The quality of being untruthful: a tendency to lie.
2. A lie.

ETYMOLOGY:

From Latin mendac-, stem of mendax (lying), from mendum (fault or defect) that also gave us amend, emend, and mendicant. Earliest documented use: 1540.

USAGE:

“The story of the founding of the Mormon church in Ohio in 1830 and its unlikely trek from there to Missouri to Illinois to Salt Lake City is one of the great adventures of the nineteenth century. It is an enthralling journey rich with acts of bravery, frailty, strength, violence, and mendacity, the most hideous being the Mountain Meadows Massacre.”
