Okay kiddo, do you know what a consonant is? A consonant is a sound you make when you close your mouth or partially close it, and it's different from a vowel like "a" or "e" where you don't close your mouth.
Now, there are some consonants that require a little extra puff of air when we say them, and those are called aspirated consonants! When we say an aspirated consonant, we blow out a little burst of air at the same time. This burst of air helps to make the sound of the consonant clear and distinct.
For example, the letter "p" is an aspirated consonant. When we say "p," we blow out a little burst of air and make a short, sharp sound that almost sounds like a little explosion in our mouth!
So next time you say a word with an aspirated consonant like "pat" or "top," remember that little burst of air that helps make the sound so crisp and clear.
