new words

I was curious as to the meanings of some words I have heard off and on for a while. I was close on inexorable, which basically means unchangeable, persistent and inevitable. I had a general idea about inculcate, which means to teach something to someone untill they get it. I really had no idea about inchoate, much less how to pronounce it. It means to be new at something, or for something to be in the initial stages. I googled the three words on a whim, so now I know what they mean. I already use inexorable, but the other two probably won't come up in conversation all that frequently.
