One of the most frequent errors is adding apostrophes where they don’t belong, particularly with plural nouns that are not possessive. Example Mistake: The dog’s are barking. (Incorrect) Correction: The dogs are barking. In this case, “dogs” is simply a plural noun, so no apostrophe is needed.

One of the most common mistakes that people make when it comes to apostrophes is using them in plurals ending in an ‘s’. For example, we are open Monday’s to Friday’s. In order to pluralise a regular noun all you usually need is to add an ‘s’. Therefore, the correct version is we are open Mondays to Fridays.

Adding an “s” or “es” makes words plural without the help of an apostrophe. One grammar mistake that drives editors crazy is the use of an apostrophe to “pluralize” a word, as in, “I bought my mom some slipper’s for her birthday.” If the subject of the sentence is already plural, however, add the apostrophe after the “s.”

Remember, the apostrophe is not used to make a word plural. Instead, you simply add an “s” to the end of the word. For example: Dogs (not dog’s) Apples (not apple’s) Cars (not car’s) Another mistake is using an apostrophe when you don’t need one.
