So the person quoted doesn't actually know what a dictionary's purpose is. It seems there are still people who think a dictionary should prescribe, not describe.

This is by no means the only case where a word's meaning has changed over time, or even reversed its meaning. "Decimated", which now means destroyed or substantially destroyed depending on one's source, once meant reduced by a proportion of one tenth.

Notice the difference in the listings between Merriam-Webster and dictionary.com. It's an old tradition with Merriam-Webster (and its predecessor Webster's Dictionary) to list the oldest definitions first. It seems newer dictionaries have reversed this practice. Speaking of reversals. :)
