About the Word:
We tend to think of irregardless as a recent coinage. Some might even claim it's a sign of the modern decline of both manners and language. But the earliest evidence of the word's use is from 1795, when George Washington was still president. It was used in a poem printed in the Charleston City Gazette, titled "The Old Woman and her Tabby," and can also be found in consistent use throughout the entire 19th century.
