What is morphology? Easiest explanation?

Morphology is like the way words are built from smaller parts, just like how you build a tower with blocks.

Think about the word happiest. It starts as happy, and then it becomes happier and finally happiest. Each step adds something new to the word. Those added pieces are called affixes, like little helpers that stick to words to change their meaning or how they're used.

Imagine you have a block labeled "cat." If you add another block on top labeled "s," it becomes "cats." That’s just like adding an suffix, which is a helper that goes after the word. Or if you put a block labeled "un" in front of "happy," it becomes "unhappy", that's a prefix, a helper that goes before.

Words can be like puzzle pieces, and morphology is how we know which pieces fit together to make new words. You already use it every day, when you read or talk! Morphology is like the way words are built from smaller parts, just like how you build a tower with blocks.
