English Vowel Sounds and Their Spellings: A Chart for Learners

English has five vowel letters, a, e, i, o and u, with y helping out. It has far more vowel sounds than that. Depending on the accent and on how you count, American English uses around 15, and the standard British accent described in textbooks has about 20. Five letters cannot cover that many sounds one by one, so English combines them, pairs them, and borrows consonants to help. The result is the part of English spelling that confuses learners most.

If you have ever written "freind", "becuase" or "beleive", or wondered why "said" and "red" rhyme, the problem was almost certainly a vowel. Consonants in English are fairly reliable. Vowels are where the choices are.

This guide gives you a chart of the main English vowel sounds, the usual ways each one is spelled, and the patterns that tell you which spelling to choose. It uses ordinary example words, with the symbols from the International Phonetic Alphabet (the system most learner dictionaries use) alongside them, so you can match the chart to your dictionary.

Why five letters have to do so much work

The mismatch has a history. English spelling was largely fixed between the late 1400s and the 1700s, around the time printing arrived. During roughly the same period, the long vowels of English moved in a series of changes known as the Great Vowel Shift. The letters stayed where printers had put them; the sounds moved on. So "name" was once said with a vowel close to the one in "father", and "time" with a vowel close to the one in "team".

English also borrowed huge numbers of words from French, Latin and Greek, often with their own vowel spellings. "Machine" kept the French i that sounds like ee. "Police" did the same. Each borrowing added another spelling to an already crowded sound.

That sounds discouraging, but it is only half of the story. Many vowel choices are decided by clear patterns, especially by where the sound sits in the word. A study led by Paul Hanna in the 1960s found that roughly half of about 17,000 common words could be spelled from their sounds using rules alone, and the reading scientist Mark Seidenberg has argued that English spelling is far more systematic than its reputation. The chart below is built to show those patterns, not just the exceptions.

How to read the chart

Each table gives a vowel sound, its symbol in the International Phonetic Alphabet, a keyword that has the sound, and the common spellings with an example of each. The first spelling listed is a good first guess in most positions, but not a guarantee.

The symbols follow American English, the accent used by most learner dictionaries in their US pronunciations. British dictionaries use slightly different symbols for a few sounds, which we note where it matters. If your dictionary uses different symbols, go by the keyword, which is the same in either accent.

Do not try to learn the whole chart at once. Use it as a map. When a word surprises you, find its vowel sound in the chart and see which spelling it used. Over time you will notice that the same few spellings keep appearing.

The short vowels

These are the vowels of short, closed words like "sit" and "cup". In most of them the plain single letter is by far the usual spelling, which is good news.

Two things stand out. First, the short u sound is often spelled with an o, especially next to m, n, v and w: some, come, money, love, won. This is a very old habit of scribes, and it covers more words than learners expect. Second, the short e sound spelled ea, as in "head", "bread", "weather" and "ready", is common enough to be worth learning as a pattern rather than as exceptions.

In British English, "hot" has a different, rounder vowel from "father". In most American English they share a sound, which is why the chart groups them.

The long vowels

Long vowels are the ones that "say their name", plus the long oo of "food". Here English has the most spellings to choose from, and the most patterns to help you choose.

The pattern "a-consonant-e", sometimes called silent e or magic e, is the single most useful line in this table. The final e is silent, but it changes the vowel before it: hop becomes hope, cut becomes cute, rid becomes ride. It accounts for a large share of long vowel spellings in short words.

The long e sound is the most crowded sound in English. Pairs such as "meet" and "meat", "see" and "sea", "week" and "weak" are spelled differently only because they mean different things. Here, meaning is your guide, not sound.

Vowels that glide, and vowels before r

Some English vowels move during the sound, from one position of the mouth to another. Others change their quality when an r follows them. Both groups have their own spellings.

Many Americans say "saw" and "caught" with the same vowel as "hot". If that is your accent, the aw sound will not feel separate, and you will simply need to learn which words use aw, au and augh.

The er sound deserves special attention. In "her", "bird", "turn", "word" and "learn", the sound is exactly the same, and five different spellings carry it. There is a partial pattern: after w, "or" is common (word, work, world, worse). For the rest, you have to know the word. Grouping them by spelling, as in a list of ir words and a list of ur words, makes them easier to remember.

The schwa: the most common vowel of all

The most frequent vowel sound in English is not in any of the tables above. It is the weak, short "uh" sound in unstressed syllables, called the schwa, and written ə in dictionaries. It is the first sound in "about", the second in "taken", the third in "pencil", and the last in "lemon", "circus" and "doctor".

The schwa can be spelled with any vowel letter, and the sound gives you no clue which one. That is why "separate", "definite", "grammar" and "calendar" are so often misspelled by everyone, native speakers included.

The best tool is a related word where the vowel is stressed and clear. "Definite" is related to "finite", where you can hear the i. "Grammar" is related to "grammatical", where the a becomes audible. We cover this in detail in the lazy vowel behind most spelling mistakes.

Where the sound sits often picks the spelling

The tables show many spellings for each sound, but you do not have to choose among all of them every time. English vowel spellings are often decided by position.

Some pairs divide the work neatly. "Ai" is used inside a word and "ay" at the end: rain, day; paid, pay. "Oi" is used inside and "oy" at the end: coin, boy; point, enjoy. "Ou" is common inside and "ow" common at the end: house, cow; found, now. The reason is an old rule of English spelling: English words do not usually end in i or u, so the y and w versions take over at the end.

The long e sound at the end of a longer word is usually y: happy, family, city, very. The long i sound at the end of a short word is often y: my, by, try, why. "Igh" appears mostly before t or at the end of a word: night, light, high, sigh.

These rules have exceptions, but they turn a choice among six spellings into a choice among two, and often settle it completely. For more on how position works, see why English has so many ways to spell one sound.

How to practice with the chart

A chart is a reference, not a lesson. Reading it many times will not make the spellings automatic, because recognizing a spelling and producing it are different skills. Producing it is the one that matters when you write.

Work on one sound at a time. Pick the vowel that causes most of your errors, for example the long a. Collect ten or fifteen words with that sound, grouped by spelling: a-consonant-e, ai, ay, and the few rarer ones. Then practice producing them from memory: have someone say each word, or play a recording, and write it without looking. Check each word and note which spelling you chose.

Spread the practice out. Recalling a word builds memory more than rereading it, as Henry Roediger and Jeffrey Karpicke showed in 2006, and spacing reviews over days works better than one long session. Mix your words too. In a 2008 study, Nate Kornell and Robert Bjork found that people learned to tell painters' styles apart better when the paintings were mixed than when each painter's work was studied in a block. Telling ai from ay is a similar task: you learn the difference by seeing the two side by side.

Spelling.School tracks this for you: when you keep missing the same pattern, such as ie and ei or a particular vowel spelling, it brings extra words with that pattern into your practice until you get it right.

What to do next

Look back at your last few pieces of writing and find the spelling mistakes in vowels. For each, find its sound in the chart and see which spelling you used and which was correct. You will probably find that two or three sounds cause most of your vowel errors.

Pick the biggest one. This week, collect words with that sound, sort them by spelling, and practice them from dictation for a few minutes a day. If you would rather have the words read aloud and scheduled for you, Spelling.School does that, with a short warm-up that finds your level first.

Questions people ask

How many vowel sounds are there in English?

It depends on the accent and on how you count them. American English uses around 15 vowel sounds, not counting the vowels before r, and the standard British accent described in textbooks has about 20, including the gliding vowels called diphthongs. Either way, there are far more vowel sounds than the five vowel letters, which is why vowels are the hardest part of English spelling.

Why does English have so many ways to spell the same vowel sound?

English spelling was largely fixed at the time of early printing, and the long vowel sounds then changed during the Great Vowel Shift, so letters and sounds drifted apart. English also borrowed many words from French, Latin and Greek with their own spellings. Some different spellings are kept on purpose because they separate words with different meanings, such as meet and meat.

What is the difference between ai and ay?

Both spell the long a sound, as in rain and day. "Ai" is usually used inside a word, before a consonant, as in rain, paid and wait, and "ay" is usually used at the end of a word, as in day, play and stay. The same pattern applies to oi and oy, and often to ou and ow.

What does the silent e at the end of a word do?

In many words, a silent e at the end changes the vowel before it from short to long. Hop becomes hope, cut becomes cute, and rid becomes ride. The pattern is often called magic e or vowel-consonant-e, and it is one of the most common ways English spells long vowel sounds in short words.

How do I know whether to write er, ir or ur?

In many words you cannot tell from the sound, because her, bird and turn use exactly the same vowel. After w, the spelling "or" is common, as in word, work and world. For the rest, it helps to learn the words in groups by spelling and to practice them from memory, so the correct form becomes familiar.

Which vowel sound causes the most spelling mistakes?

The schwa, the weak "uh" sound in unstressed syllables, causes the most trouble for native speakers and learners alike. It appears in words such as separate, definite and calendar, and it can be spelled with any vowel letter. The most reliable fix is to find a related word where the vowel is stressed, such as finite for definite.
