Definition & Meaning of "consonant"

What is a "consonant"?

A consonant is a speech sound produced when airflow is partially or completely blocked in the vocal tract. Unlike vowels, which are produced with an open vocal tract, consonants involve some form of closure or narrowing, creating distinct sounds. In the English alphabet, consonants include letters such as "b," "c," "d," "f," "g," "h," and so on. Consonants can be classified based on their place and manner of articulation, such as stops, fricatives, and nasals. Understanding consonants is essential for phonetics, spelling, and pronunciation in language.
