Apostrophes in possessive forms


Grammarly corrects use of apostrophes in sentences similar to the following:

She told her mother that she was sleeping at Katie's house for the night.

Then she would drive to Brent's.

She picked up Katie's kitchen phone and called her boyfriend. Grammarly omits apostrophes.  I think this is incorrect.

You're not the first person to notice this.  The program doesn't actually omit the apostrophes, it highlights the word as misspelled.  Since Grammarly Answers is a Q&A site for the discussion of grammar, your should email your complaint to Support.

Thanks. In fact, in the past, Grammarly did not highlight the possessive use of apostrophes as misspelled words. I wonder, why the change?

I've noticed that the program only does it with certain proper names. It doesn't like the possessive form of Kevin, but it has not problem with the possessive form of Jody.

Software is often not very bright. It is a challenge for "natural language" driven software to disguish between a possessive and a plural. I am told that Grammarly includes a set of "rules" that help it distinguish between the two by the context, but in my experience, those rules are far from complete. I am also told that Grammarly chose to err on the side of caution because the misuse of possessives and plurals is a frequent mistake. That results in numerous false positives.


Rather than telling me that my writing IS wrong, I interpret Grammarly as saying my writing MAY be wrong.  I just go back and double check to make sure I used the right form.
