IPA: /dɪsˈɒnəsti/
KK: /dɪsˈɑnəsti/
The quality of being untruthful or not honest; the act of deceiving or lying.
His dishonesty was revealed when he was caught lying about his qualifications.
Dishonesty is formed from "dis-" (meaning apart or away) and "honest" (from Latin "honestus", meaning honorable or respectable) and the suffix "-y" (indicating a state or condition). The word describes a state of being away from or lacking in honor or integrity.
Think of 'dis-' meaning apart and 'honest' meaning honorable — dishonesty is the state of being apart from honor.
