Ignoble is an adjective that means not honorable.

The root word of ignoble is noble, which comes from the Latin word nobilis (KNOW bee lease) meaning ‘high-born.’ As time went by, the word’s definition shifted to mean ‘honorable.’ With our word of the day, the prefix I-G was added and it meant ‘not honorable.’

Terry’s ignoble behavior caused him to be fired from his job at the bank. Embezzlement is usually not considered an honorable thing to do in that industry.
