I saw this in a company document.
Problem:
“Irregardless” is meaningless in that it means the opposite of what is intended.
Explanation:
People use “irregardless” when they mean the adverb “regardless”. The confusion could come from the fact that some words can be negated with the “ir” prefix. “Irreverent” is the opposite of “reverent”; “irregardless” is meaningless, on the other hand.
Solution:
“Regardless”
I heard this during a conference call.
Problem:
“Today” is an adverb, so preceding it with the preposition “on” is incorrect.
Explanation:
“Today” already tells you when.
For example, the answer to “When will the bus arrive?” could be “The bus will arrive today.”
In contrast, “Sunday” is a proper noun, not an adverb, so the answer to “When will the bus arrive?” could be “The bus will arrive on Sunday.”
In other words, the days of the week, which are proper nouns, require the “on” preposition to tell you when, whereas “today” already tells you when.
Solution:
“It will start today.”
I saw this on an Ikea sign.
Problem:
“Everyday” is an adjective, but an adverb is required here.
Explanation:
“Everyday” tells you what. For example, an “everyday event” is an event that occurs daily. In other words, “everyday” is an adjective; it modifies a noun (such as “event”). “Everyday” in this example tells you what kind of event it is. In contrast, “every day” tells you when. For example, “It happens every day.” The goal of the sign maker is to tell the reader when the store is open.
Solution:
“Every Day – 10 AM to 9 PM”
