The difference between vowels and consonants is that you impede the flow of air in some way for consonants, but not vowels.Previous Fact Next Fact
Key difference: The alphabets a, e, i, o, and u are called as vowels in the English language. Consonants are all the other alphabets of the English language, except the vowels. At times, the alphabet 'y' is also considered as a vowel. Merriam-Webster defines a vowel as "a speech sound made with your mouth open and your tongue in the middle of your mouth not touching your teeth, lips, etc." The letters representing the vowels are a, e, i, o and u. Vowels, along with consonants, are an intrinsic part of English elementary education. Learning vowels is absolutely crucial to a person's grammatical and vocabulary skills as well. While using vowels in writing a piece of text, one must take into consideration an important rule associated with doing so. In this sentence, the word 'apple' starts with the letter 'a'. So, the word 'an' is placed to satisfy the grammatical rule associated with vowels.
Consonants are voiced out completely in contrast to vowels, which are the speech sounds produced by the free flow of air exhaled from the mouth. Along with vowels, consonants are crucial to a person's understanding of the phonetics concerned with different words. Consonants are represented by all the English language alphabets, other than the five vowels. Unlike vowels, consonants are not tagged along with any rules of grammar. An important point to note about the vowels and consonants is the letter 'y'. The alphabet 'y' is considered both a vowel and a consonant by many people. In the United States, children are taught that the vowels consist of the alphabets a, e, i, o, u and y. The rationale behind this is the speech sound produced while voicing out this alphabet in different words. The alphabets a, e, i, o, and u are called as vowels in the English language. Vowels always have to be preceded by the word 'an', instead of 'a', 'the', 'they', etc.
