ELI5: Explain Like I'm 5

Phonological hierarchy

Imagine that you have a toy box and all your toys are inside. You need to organize them so that you can find them easily when you want to play with them. You decide to sort the toys by size, with the smallest ones at the top and the biggest ones at the bottom.

In the same way, our brains organize the sounds of our language in a hierarchy based on how they are pronounced. This is called the phonological hierarchy. It starts with individual sounds, called phonemes, which are like the building blocks of words.

Next comes syllables, which are made up of a combination of phonemes. For example, the word "cat" has one syllable because it has only one vowel sound and is made up of three phonemes: /k/ /æ/ /t/.

Then there are words, which are made up of one or more syllables. Finally, sentences are made up of words and are the highest level of the phonological hierarchy.

Just like organizing your toys makes it easier to find them, the phonological hierarchy helps us to understand and produce language more easily. By breaking down language into smaller components, we can better understand how it works and communicate more effectively.
