Preconceive → It is formed from "pre-" (meaning before) and "concipere" (meaning to conceive or form an idea). The word "preconceive" means to form an idea or opinion before having the necessary information or experience.
Think of forming an idea 'before' ('pre-') actually 'conceiving' ('concipere') it — that's why preconceive means to have an idea in advance.
