dictionary words definitions

I need a list of words, without definitions, to serve as a database for a computer program I'm writing that works with English words. The program will parse through the file and compare entries with the words in the file. Does anyone know where I can find a list like this?

"it" "the" "a" and "is"? Think about it!

also, how many are there really?

I see a lot of people who say feminism is about equality "because the dictionary says so." That's the end of the argument in their opinion. However, many of these same people will use the word "patriarchy" to describe the whole system of oppression of women in society. My dictionary says that patriarchy is a familial system where the father is head of a household. It never says anything about society in general (that definition is paraphrased slightly). If you really think dictionary definitions of words don't change over time, try this one out. Next time you're in public and you're in a happy mood, yell out "I'm so gay!" and see how people react. Because gay means happy, right? I mean, that's what dictionaries said for a long time. So which is it? Do we go by the dictionary definitions of words, or by how they're used in society? I'm not saying that feminists aren't for equality necessarily, but I see this double standard and have to ask why some people are allowed to change the definitions of words and others aren't. I've seen a few other dictionaries on the Internet now (the one I referenced is one of those old-fashioned paper kinds) and I've seen both definitions that feminism is about equality, about women's rights only. Also, some of them say about patriarchy that it's a familial structure based on fathers being the heads of households and that it's a societal system based on that. So I guess after seeing that we're all right now. Dictionaries are changing their definitions. Amanda- This isn't calling you out. I know it looks like it. I've thought about this for a while. You just kind of reminded me about it. Untamed Rose- Conservative is a good one, because it means different things in different countries. That's at the same time. Amanda- One person doesn't change a word's meaning. Lost of people use feminism to mean only fighting for women's rights-including many feminists themselves. Amanda- I like your backtracking. You had a decent argument until you shot yourself in the foot by using patriarchy in a metaphor but say only feminists can define feminism. I'm waiting for Yahoo to delete this. They've deleted a lot of stuff of mine lately. What if somebody used feminism as a metaphor for man-hating? Amanda- Thank you for proving my point. You just used a word in a metaphorical sense but tell me I can't do the same. That's what I'm getting down to in a way. Why can you do it and I can't? There are enough feminists out there who are man-haters, or at least think women are superior to men, to qualify for that definition. I've met several myself. By the way, I've never used the word in that way, but I was proving a point. Amanda- I'm not the hypocrite here. Flamespeak- I noticed it actually. I didn't really think much about it though.
