Linguistic Pet Peeves

I was listening to the Diane Rehm Show on NPR this morning, and guest-host Susan Page said "We're not getting very many kudos by email today." Well, of course you're not. Kudos is not a plural noun, so how can you get many of them? There's no such thing as a kudo. I kind of expect that kind of thing from hoi polloi but not from NPR presenters!

Now, don't get me wrong, I'm not a pure prescriptivist when it comes to grammar. I understand that language changes. I also understand that it's not right to try to shoe-horn English into the grammatical rules of Latin, which is why I have no problems ending sentences with prepositions, and splitting infinitives is fine.

However, some things just annoy me. The most common annoyance, especially this side of the pond is the hypercorrection "He and I" in the accusative. I see it lot on web pages these days. This is a picture of John and I. No, it isn't. I believe it came about from poor teaching. It became common for people to use "John and me" in the nominative. John and me are going to watch a movie. The teacher told them "It's not 'John and me', it's 'John and I'". That's all well and good, except the teacher failed to continue with "... when it's the Subject of the sentence." The student incorrectly learnt, therefore, that it's always "John and I". If you're not sure of which is correct, just be selfish and leave John out of it. Me is going to the movies. No, "I am going to the movies" is correct here, as I'm sure you know, so "John and I are going" is the correct form with both people. This is a picture of I is clearly wrong, it should be "me" there. Therefore, "This is a picture of John and me" is the correct form. So, be selfish, leave the other person out, and get it right!
