Precisely accurate-fuck the dictionary!

I'm thinking about accuracy and precision. Trying to find the defintions for myself without looking them up and I'm not sure I'm geting it right. Precision is maybe defining your objective to within a very small limit. And accuracy relates to the ability to get it right many times over? I don't know if that's right though. It's the best I can think of. If anyone has a better explanation that would be cool. I'm trying to resist getting it from the dictionary. I don't know why, but sometimes I have an aversion to my words being so accurately (ahem) defined. I like to come up with my own approximations. I think it comes from me learning to read really early. I think I read full novels in like 1st maximum 2nd grade (though Matt says this is very unlikely) and so I became used to reading words that I really didn't know specific definitions for. So I would just decide what they meant after I had read them enough. Sometimes I have been very wrong. Just like last year I had heard the word bellicose many times and my defintion of "something about being good" didn't pan out, and I finally looked it up and it means "warlike". Who wudda thunk it? Usually anything with 'bel' means good, beneficient, etc. I guess the double 'l' really changes things. So maybe I am just egoistic and hate learning things from others and should just read the fucking dictionary. This reading words without hearing and/or looking them up also means I am pretty bad at pronouncing some big words. I remember hearing the word inevitable in 7th grade and never connecting it with the written word which I had (this time correctly defined) read many many times, but always pronounced in-vite-able in my head. Whatever, I still don't like dictionaries too much. Foreign language ones are okay I guess. What the fuck? So anyway, if you wanna help me with accuracy and precision please do so, just don't give me the dictionary definitions. I wanna hear what you think.
