Language changes

The most significant convention is language. Language just is a and the dictionary records use. It is descriptive, not prescriptive. They don't tell you how to use words, they record the way words are actually used, and offer a guide in the most popular uses.

Just today, for instance, we hear of the addition of a new meaning for 'wedgie'. Here's the definition:

wedgie: noun. a prank in which the victim's undershorts are jerked upward so as to become wedged between the buttocks.

A few new words appeared as well. Namely, Al Qaeda, blog, cargo pants, irritable bowel syndrome and partial-birth abortion.
