Definition: Something that must be gained in order to gain something else

Alright class, settle down, let’s take a look! That dictionary definition is spot on, you see – it really captures the meaning of “prerequisite.” Let's break it down with a little rhyme for you: A prerequisite , a key to the door, Something you must know, and nothing more. Before you can learn something new and bright, You need this foundation, shining just right! Essentially, it means something you absolutely need to have before you can tackle something else. Think of it like building blocks – you can't stack them high if the base is weak, right? Let’s look at some examples: To take Calculus: You usually need Algebra first, you see! To drive a car: You must learn to read and write with glee! A job application: Might ask for experience, you agree? So, “prerequisite” – it’s all about preparation and knowing what's needed ahead of time. Do you have any questions about that, class?
