I saw all three of these at a fitness center.
Problem:
Inconsistent use of a possessive apostrophe makes it meaningless.
Explanation:
“Kid’s Club” says that there is one kid and that he or she has a club. “Kids’ Club” says that there are many kids and that they have a club. “Kids Club” says that there is a club for kids.
Solution:
Know why you’re using a possessive apostrophe.
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”
