So, after including the following content in a Craigslist post, I thought I would add it, here.
1) Merriam-Webster online dictionary can be found at: http://www.m-w.com (Will open in new window).
2) Step one: open browser of your choice.
Step two: type Google.com in the address bar. Press 'enter.' (Yes, this is technically two steps, but clearly falls under "common-knowledge," and I have faith in you).
Step three: type "insert word in question here" and "definition" in the long skinny white box where you tell it what you're searching for. (Note: you do not have to type the word "and," but if you forget, it's okay; Google will ignore it, anyway. You may or may not use quotation marks; that falls under boolean searches, but we won't go there).
Step four: hit your enter key.
Step five: read suggested material.
...Google is your friend.
Hope this helps.
