Vowels

What Are Vowels? (with Examples)
The letters A, E, I, O, and U are called vowels. The other letters in the alphabet are called consonants.More about Vowels
Every Syllable Has a Vowel Sound
A vowel sound (but not necessarily a vowel in the actual spelling) will be present in a syllable.Interesting Words
Here are some interesting words with regard to their vowels:- The word "Iouea" (a genus of sea sponges) contains all five vowels and no other letters. (Being the name of a genus (i.e., a proper noun), it is written with a capital letter. Also of note, it is the shortest word with four syllables.)
- The words "abstemious" and "facetious" contain all five vowels in order.
Is Y a Vowel?
Using the formal definition above, the letter Y in words like "hymn" and "shy" is also a vowel. However, in words like "beyond" and "yes," Y is a consonant because the breath is partly obstructed.So, is Y a vowel? Well, sometimes it is, and sometimes it isn't, which is why it is often called a semi-vowel. The argument for classifying Y as a consonant (which most do) is based on this: When Y is a vowel, it is really just an I. When it is a consonant, it is being itself.

Video Lesson
Here is a video summarizing this lesson on vowels.Short and Long Vowels
In English, the sounds of the vowels are group into two pairs: short vowels and long vowels. The short vowels are pronounced as follows:- "a" as in "bat"
- "e" as in "bed"
- "i" as in "bit"
- "o" as in "bog"
- "u" as in "but"
- "a" as in "haze"
- "e" as in "he"
- "i" as in "hi"
- "o" as in "hope"
- "u" as in "human"
Some alternative spellings for the short "e" vowel:
- many
- bread
- said
- leopard
- pain
- prey
- pray
- puree

Why Vowels Are Important
Here are two good reasons to think more carefully about vowels.(Reason 1) Be clear on when to use "an" and "a."
Use "an" (not "a") before a vowel sound. The important word here is sound.- an apple.
a apple.
("An" is correct because "apple" starts with a vowel sound (and a vowel for that matter).)
- an RTA.
a RTA
("An" is correct because "RTA" starts with a vowel sound ("ar"), even though the first letter is not a vowel.)
- An unidentified man with a unicorn tattoo rented a house an hour ago.
- Becoming a eunuch wasn't a one-off deal – it was a two-off deal.
(Reason 2) Use assonance to add rhythm and musicality to your writing.
Assonance is a literary technique created by repeating the same vowel sound in neighboring words. It is used by lyricists and poets to encourage their readers and listeners to consider the near rhyme created by the assonance. (NB: Assonance contrasts with consonance, which is a similar literary technique in which nearby words repeat the same consonant sound.)Here are some examples of assonance:
- His fleet feet seem impossible to beat.
- "A host, of golden daffodils" (Extract from "I Wandered Lonely as a Cloud" by poet William Wordsworth)
- "Hear the mellow wedding bells" (Extract from "The Bells" by American writer Edgar Allen Poe)
Here, for comparison, is an example of consonance:
- I earn my keep by cracking locks or picking pockets.
Key Points
- Use "an" if the next word starts with a vowel sound.
- Use assonance (repetition of the same vowel sound in nearby words) to compel your readers to think more deeply about your word choice.
- Do you disagree with something on this page?
- Did you spot a typo?
