Vowels vs. Consonants — What's the Difference?
By Tayyaba Rehman — Published on October 17, 2023
Vowels and Consonants are both types of letters in the alphabet. Vowels include the letters A, E, I, O, U, and sometimes Y, while Consonants are all the other letters that are not vowels.

Key Differences
Vowels and Consonants serve as foundational building blocks of words in the English language. A word in English cannot exist without a vowel, whereas words without consonants do exist. Vowels create the vocal sounds that resonate, while Consonants provide closures or constrictions of vocal tracts.
The English language recognizes A, E, I, O, U, and occasionally Y as Vowels. They can stand alone and be a word on their own, like "a" or "I". On the other hand, Consonants are letters that are not vowels, and they require a vowel to form a syllable. Examples of Consonants include letters like B, C, D, F, and G.
Vowels offer more vocal variation than Consonants. Each vowel can be pronounced in a short or long manner, giving a word its specific sound. Consonants, conversely, typically have one specific sound that doesn't change based on the word's context, although there are exceptions like the soft "c" in "city" versus the hard "c" in "cat".
Phonetically speaking, Vowels are voiced sounds made without significant constriction of airflow in the mouth. Consonants involve a greater obstruction of the oral passage, often using the lips, teeth, or tongue. For instance, the "b" sound in "bat" is formed by briefly blocking airflow with the lips.
In written English, both Vowels and Consonants are essential for creating meaning. They come together to form syllables, words, and sentences. Vowels often carry the tonal quality of a word, while Consonants provide the structure and rhythm.
