Definition: Excess of material, useless by-products or damaged, unsaleable products; garbage; rubbish.

Alright class, settle down now, let’s take a look at this word – “waste.” The dictionary gives us a pretty clear picture, don't you think? It says it's about things that aren't needed, things we discard. Let’s break it down a little bit with a rhyme: “Waste” means to let something go, A surplus left, a needless flow. Like broken toys or scraps of thread, Or leftovers from a meal instead! It can be material, like cardboard boxes tall, Or by-products, answering nature’s call – Like seeds leftover after planting bright, Or damaged goods that aren't quite right. Think about it - if you build a castle grand, And have extra bricks upon the land, Those extra bricks are considered waste, see? Not needed for the structure, happy and free! So "waste" isn’t just trash, though garbage is part of the scene, It’s about something that's unnecessary , it would seem. Do you have any questions about this word, class? Let's discuss!
