Definition Exercise
As a grampa, my babysitting is sometimes done at their house and sometimes at my house. When I go to my son's houses I usually take a book to read in the event the tykes take a nap. One day a few months ago I went to sit and forgot the book. I had a legal pad out in the car so I decided to try my hand a putting together some formal definitions in an effort to hone my skill at it. I started out with Rand's definition of table at the top of my list as a model. So here for your perusal and criticism is my short list.

Admittedly this is a short list and only very simple things defined. While doing this I refused to consult a dictionary for assistance for two reasons. One, many dictionaries don't give genus/differentia definitions and second, I need to get better at identifying definitions myself. So if you're a mind to, spare no criticism.
