Here's a breakdown:
* Speech sound: It refers to a sound that is used in spoken language.
* Partially or completely obstructing the flow of air: This is the key characteristic of consonants. Unlike vowels, where air flows freely through the mouth, consonants involve some kind of blockage or narrowing of the airflow. This blockage can be created by the tongue, teeth, lips, or the soft palate.
* From the lungs: Consonants, like all speech sounds, are produced by exhaling air from the lungs.
Examples of Consonants:
* b, d, f, g, h, j, k, l, m, n, p, r, s, t, v, w, x, y, z
Key Differences from Vowels:
* Airflow: Consonants restrict airflow, vowels allow free airflow.
* Sound Production: Consonants are produced by obstructing the airflow, vowels are produced by shaping the air as it exits the mouth.
Importance of Consonants:
Consonants are essential for creating the structure and meaning of words. They provide a framework that vowels can fill, adding richness and complexity to spoken language.
