IPA: /ɪˈfrʌntəri/
KK: /ɪˈfrʌntəri/
A type of boldness that is shameless or disrespectful, often showing a lack of regard for others' feelings or opinions.
She had the effrontery to ask for a raise after being late to work every day.
Effrontery is derived from the French word 'effronterie', which comes from 'effronté' (meaning shameless or impudent), itself formed from the Latin 'frons' (meaning forehead) with the prefix 'e-' (meaning out of). The term originally referred to someone who is bold or brazen, as if they are putting their forehead forward without shame.
Think of someone being so bold that they put their 'forehead' ('frons') out there without any shame ('effronté'). This helps you remember that 'effrontery' means shameless boldness.
