Here's a breakdown of why this is:
* Consonants are typically produced with a closed or partially closed mouth. This restriction of airflow creates a "consonant sound."
* Vowels are typically produced with an open mouth. This allows for a free flow of air, creating a "vowel sound."
* Consonants and vowels often work together to create syllables. The consonant provides the "starting point" or "stopping point" for the syllable, while the vowel provides the "core" sound.
Example:
The word "cat" has the following sounds:
* C: A consonant produced by partially closing the mouth and creating a "k" sound.
* A: A vowel produced with an open mouth, allowing for a free flow of air.
* T: A consonant produced by completely closing the mouth and then releasing the air quickly.
So, the "c" and "t" sounds are considered "consonants" because they are produced with a closed or partially closed mouth, creating a friction or obstruction. These sounds "sound together" with the vowel "a" to create the word "cat."
