pre·req·ui·site noun, adj.
pronounced: (prēˈrekwəzət/)
Something that’s necessary and required prior for something else to occur.
I first heard of this word when I had attend the registration workshop. I also learned about it there. But last week during English class, the term had also came up when Prof. Rosen quickly mentioned classes and registration. Some classes are needed before others is what this means in college terms.
