Okay, grammar pet peeve time: Apostrophe abuse. It needs to stop. Now.
There are only two instances in the English language in which apostrophes are used:
1) Contractions, as in: you are = you’re, or have not = haven’t, or I am = I’m. Just keep in mind that the apostrophe takes the place of the missing letter(s); if you take a letter out to combine (contract) two words together, place the apostrophe where the missing letter would have been written.
2) Possessives, as in: Steve’s hat (the hat belongs to Steve), or today’s specials (specials on for today)
Never, I repeat NEVER should an apostrophe be used to indicate a plural!! Never, EVER. If you see it used as a plural, it’s wrong – even if it’s on a tombstone (see the image below).
In the illustration on the right, “Alway’s there for us,” it obviously means “Alway is there for us.” But who is Alway? I thought Mary was trying to rest in peace here… It’s just wrong on so many levels, because it’s not even a plural (which they were aiming for), but an adverb.
Let’s (as in “let us”) look at another very common mistake: 1) it vs. 2) it’s vs. 3) its:
1) “It” is fairly straightforward; it is the third person singular pronoun (used in place of a noun) for objects or gender-neutral references; e.g. The chair is red = It is red.
2) “It’s” is the contracted form of “it is”, as in It’s raining or “it has”, as in It’s been a long time since we saw each other last.
3) “Its” is the possessive form of the third person singular pronoun: “the dog’s paws” = “its paws” REMEMBER: You would never spell “his shirt” as “hi’s shirt”, or “her skirt” as “he’r skirt”; in the same way you should never use the contracted form as the possessive form of it.
It’s not “CD’s” or “DVD’s” as the plural form; this is actually the possessive (which therefore requires an object for that subject’s possessive form, as in the CD’s case), and I find myself asking, “CD’s what?”
If you want more examples, from tombstones to shop signs to tattoos that are embarrassingly wrong, take a look at www.apostropheabuse.com. Okay, pet peeve appeased. Glad to get that off my chest.
