Thought is the process of using your mind to consider something. It can also be the product of that process: an idea or just the thing you're thinking about.

Thought can also refer to the organized beliefs of a period, individual, or group. If you're writing an essay about the Reformation, you'll probably want to summarize early Catholic thought regarding free will and predestination. This word can also be used to describe a personal belief or judgment you can't prove or be entirely certain of.
