I have reached my quota of listening to grammatical errors today. I will confess to not always being perfect in my sentence structure (and fat-fingering into typos periodically). My worst offense tends to be dangling prepositions. I know this is incorrect, but sometimes I get lazy.
I am, however, a stickler for matching tense. Past participles are the worst! I just heard an announcer in either the Tigers/Royals or the Reds/Padres game utter the phase "should have ran." It is "should have RUN". If one more college educated person in my work place (or household) says "should have went" instead of "should have gone," I think I am going to lose what is left of my sanity. I also overheard a colleague state that they "seen someone." AAARRRRGGGHHHH.
My latest nitpick is the phrase "I have got to." The word "got" is totally unnecessary, yet usage of this phrase has become so commonplace, it's easy to overlook the fact that it is off kilter.
OK, enough of my ranting. What are some of YOUR pet peeves?
