A lot means more than one thing. You can buy a lot....a piece of land...to build a house on. It is a plot of ground, usually a vacant lot, with nothing on it. A lot can mean "a whole lot"....such as "I like you a lot". A lot can mean many or much of something, such as, "I bought a lot of apples". I don't like spinach a lot, but I do like to eat a lot of carrots.

alot is not considered a word, and a lot is two words.

'alot' is a common mispelling. It is not a word. The correct word would be "a lot" (two words).

"A lot" indicates an amount (or, in Gena's example, a piece of land). "Alot" is a misspelling but, according to blogger Allie Brosh, it is a hairy beast: http://hyperboleandahalf.blogspot.com/2010/04/alot-is-better-than-you-at-everything.html Reading it gave me Alot of Happiness.
