“Notice how few online dictionaries even bother with word etymology now?”

FWIW, my source did, had to click on “Word Origin”.

My pet peeve: improper use of "that" instead of "who". Example:

He was the man that robbed the store.

It should be:

He was the man who robbed the store.

I hear this one butchered fairly regularly on the evening news.

One word I don't like is portmanteau, which in English is used to mean a word created by parts of two or more words. The problem is it's a French word for a saddlebag or similar such case or bag. I think a better English word would be "mashup".
