What is the difference between monosyllabic and polysyllabic words?

The difference between monosyllabic and polysyllabic words lies in the number of syllables they contain:

* Monosyllabic words have only one syllable. These are words that can be pronounced with a single, uninterrupted sound.

* Examples: cat, dog, run, jump, book, sun.

* Polysyllabic words have more than one syllable. These words require multiple vowel sounds to pronounce them.

* Examples: happy, beautiful, elephant, incredible, understand, celebration.

Here's a simple way to remember:

* Mono means "one"

* Poly means "many"

So, monosyllabic means "one syllable," and polysyllabic means "many syllables."
