text: why do so many people use apostrophies when they are not necessary? for example, suvs is correct.  not suv's.  also, "it's" means "it is."  the possessive form is "its." i agree with you 100%.  but dollhaus is correct about suv's - i remember learning it that way in the 1980s.  also for numbers - 80's and 90's, as well as 80s and 90s, have both been considered correct at one time or another.  but what really irritates me the most are the apostrophe's used for plural's.  that just looks incredibly ignorant!  it gets confusing, too, when people use them for their plurals but not their possessives.  the boy's played with the dogs toy's today.  this book is hers'.  i knew someone who did this a lot.  i just hate reading things like that, because i usually end up having to read it a couple of times to make sure i understood it correctly.    i had a manager one time who completely understood - he compared it to someone who was musically inclined hearing a note that was out of tune.  a grammatical error stands out to some people the way a sour note stands out to others.  i am definitely one of the former.  not to say that i don't make errors myself, but i try to correct them as i go.  a lot of people just don't care to make the effort.  another thing that really irritated me - on one of my son's computer games, it uses it's instead of its.  these games are supposed to be designed to teach children, not promote ignorance!
