Adverb: Regardless (rih-GAHRD-lus)
Definition: Despite everything.
Sample sentence: The weather forecast called for wind and rain, but Susan decided to continue with her plans regardless.
Footnote: Poor “regardless” became embroiled in a usage scandal through no fault of its own when people began using “irregardless” as its synonym (probably blending “irrespective” and “regardless”). “Irregardless” originated in dialectal American speech in the early 20th century, and usage commentators have been decrying it since the 1920s, often declaring “there is no such word.” “Irregardless” does exist, of course, but it tends to be used primarily in speech and it is still considered nonstandard. “Regardless” is greatly preferred.
