English spelling and pronunciation: why English is so weird

If you have ever wondered why knife is spelled with a k that you do not say, why though, through and tough end the same way but are pronounced in three different ways, or why island has an s that nobody pronounces, you are not alone. Some languages, Spanish among them, are written almost the way they sound, and that is why English spelling is so baffling for many learners. But it has an explanation, and understanding it helps you predict the pronunciation of many words you have never seen.

Don’t worry, because English is not as chaotic as it looks: it is a language with a very complicated history, and that chaos follows patterns. In this guide I explain the five historical causes of spelling oddities, what the Great Vowel Shift was, why there are silent letters (with tables of words and IPA), how the «magic e» works, how all this compares with Spanish and which practical rules really help. I also give you my map of the pronunciation series so you know where to go next. At the end there are thirty practice sentences with answers. Let’s get started! 🙂

Why English is not written the way it sounds

In Spanish almost every letter has one sound. In English, 26 letters have to represent about 44 sounds, and the 5 vowel letters have to cover 20 vowel sounds between vowels and diphthongs. But that only explains why there is a mismatch, not why it is so big. History explains that, and this video by the linguist Arika Okrent tells it in three minutes (it is in English and has subtitles):

In short, there are five causes. I tell them in my own words, with my own examples.

The five historical causes

1. Spelling was fixed while pronunciation was changing

Around the year 600, the missionaries who arrived in England used the Latin alphabet to write a Germanic language with sounds that Latin did not have. The scribes managed as best they could, and for centuries spelling reflected pronunciation fairly well. But from the 15th century the printing press began to fix spellings just as pronunciation was changing at full speed. The result is that today’s spelling is a snapshot of the English of about 500 years ago, and the language has kept evolving since.

2. Sounds that were lost

Many silent letters used to be real sounds. In knight both the k and the gh were pronounced, the latter as a harsh sound like the Scottish ch in loch. In knee and write you could hear the k and the w. Over the centuries those sounds disappeared, but the letters stayed. If you want to see how the sound of gh changed, all the detail is in my guide to GH pronunciation.

3. The Great Vowel Shift

Between roughly 1400 and 1700, all the long vowels of English changed their sound. This is the so-called Great Vowel Shift, and we will look at it in more detail in a moment. It happened just as spelling was being fixed, so today’s vowels are written the way they were pronounced before the change.

4. The French of the Normans

After the Norman conquest of 1066, French was for centuries the language of the court, the law and the university in England. That left an enormous amount of French vocabulary and spellings (sausage, chef, garage). Very often the answer to «why is it spelled like that?» is «because that is how it was spelled in French». You can see it in the pronunciation of CH, which sounds like «sh» in French words, or in the words ending in -age, where garage and massage keep their French sound.

5. Letters that were added on purpose (and loanwords)

In the Renaissance, some scholars enthusiastic about Latin and Greek wanted words to reflect their classical origin better and added letters that had never been pronounced. That is how the b of debt and doubt, the l of salmon, the p of receipt and the s of island arrived. The last one does not even come from Latin insula but from Old English. On top of that come the words English borrowed from other languages while keeping their original spelling, such as colonel, whose spelling is Italian and whose pronunciation is French.

The Great Vowel Shift

To understand the spelling of vowels, imagine that in medieval English the vowel letters were read more or less as in Spanish or Latin. Then the change came: every long vowel moved higher in the mouth, and the ones that were already at the top became diphthongs. Spelling did not notice. That is why bite is written as if it were «beet» but sounds /baɪt/:

Listen to the six words:

Notice that the vowel letters i, a, e, o, u in the spelling look like the Spanish ones (as in time with its «i») and that is why they confuse us: they reflect the sound from before the shift. If you want to see how English vowels sound today, with their pairs, you have them in my guide to short and long vowels.

Silent letters

Most silent letters can be explained by one of the five causes: they were sounds that were lost (knee, write), they were added for scholarly reasons (debt, island) or they come from other languages. These are the most frequent ones, with their pronunciation:

At the start of a word: kn, wr, gn, ps, pn

Listen to the words, one after another:

At the end of a word: -mb, -mn, -bt

Listen to the words, one after another:

In the middle of a word and other silent letters

Listen to each row, from top to bottom:

And there is one combination that deserves its own guide: the gh of night, though or daughter, which is sometimes silent and sometimes sounds /f/. It is explained with all its words in the guide to GH pronunciation.

The «magic e» and clues for vowels

The silent final «e» is also a consequence of history: in medieval English it was pronounced, and today it no longer sounds, but it still does a very important job: it lengthens the previous vowel (and turns it into the sound it has in the name of the letter, which is the one left after the Great Vowel Shift). That is why it works as a rule:

Listen to each pair, from top to bottom:

And one more clue with double consonants: hopping (with a double p) keeps the vowel short /ˈhɒpɪŋ/, while hoping (with a single p) lengthens it /ˈhəʊpɪŋ/. The double consonant «protects» the vowel.

One sound, many spellings (and the other way round)

Two opposite phenomena explain a large part of the mismatch. The first: the same sound is spelled in many ways. For example, the sound /iː/ has eight common spellings:

Listen to the eight words: they all share the same sound:

The second: the same spelling is pronounced in many ways. The letter a, for example, sounds different in each of these words, and the combination ough sounds in many different ways (you have it in the guide to GH):

Listen to how the letter a sounds in each word:

What is predictable: the practical rules

So much oddness does not mean there are no rules. These are the guidelines that will help you most, and each one has its own guide:

• Endings are very reliable. -tion sounds /ʃn/ (nation), -ture sounds /tʃə/ (picture), -age sounds /ɪdʒ/ almost always (village) and -ed sounds /t/, /d/ or /ɪd/ depending on the previous sound. See the words in -ture, the words in -age and the pronunciation of -ed.
• A silent final «e» lengthens the previous vowel (cap and cape).
• Double consonants protect the short vowel (hopping and hoping).
• ch depends on origin: /tʃ/ in English words, /k/ in Greek ones and /ʃ/ in French ones (CH guide).
• Learn by word families, not one by one (-ight, -ought, -ear…). That is how I do it in the guide to bear, beer, bird and beard.
• When in doubt, look at the IPA. It is the one place with no traps. I explain it in the phonetics guide.

My map of English pronunciation

This guide is the entry point to a series. Depending on what you find hardest, start with one or another:

Common mistakes when reading English

• ❌ Pronouncing every letter: «k-nife», «w-rite». → ✅ Silent letters are not pronounced: knife /naɪf/, write /raɪt/.
• ❌ Reading vowels as in Spanish: time as «teem-eh». → ✅ It sounds /taɪm/: vowels do not sound the way they are written.
• ❌ Reading debt or doubt with the b. → ✅ They are /det/ and /daʊt/.
• ❌ Pronouncing the s of island. → ✅ It is /ˈaɪlənd/.
• ❌ Pronouncing -age like Spanish «-aje»: «mensaj». → ✅ It is /ɪdʒ/: message /ˈmesɪdʒ/.
• ❌ Pronouncing the l of walk or calm. → ✅ They are /wɔːk/ and /kɑːm/.
• ❌ Trusting spelling to pronounce new words. → ✅ Check the IPA or listen to an audio first.

Tips for mastering spelling and pronunciation

• Listen before you read. When you learn a new word, hear how it sounds before you say it, and do not trust what you see written.
• Always read with the IPA next to it. It is hard at first, but in a couple of weeks you will read it effortlessly.
• Group words by families. night, light, right in one group, knife, knee, know in another.
• Use the clues: the final «e», double consonants and reliable endings.
• Do not get frustrated with exceptions. Even native speakers make spelling mistakes: it is normal.

Frequently asked questions about English spelling

Why is English spelled differently from how it sounds?

Because of history: spelling was fixed in the 15th and 16th centuries while pronunciation kept changing (above all with the Great Vowel Shift), and English has also taken many words from French, Latin and Greek while keeping their spellings.

What was the Great Vowel Shift?

A set of pronunciation changes, between roughly 1400 and 1700, in which all the long vowels of English moved higher in the mouth or became diphthongs. That is why bite and time are written with an i but sound /aɪ/.

Why are there silent letters in English?

Because they were real sounds that disappeared (knee, write), because they were added for scholarly reasons (debt, island) or because they come from other languages.

Why is English spelling not reformed?

It has been tried, but it is very difficult: English has many different accents and there is no single pronunciation to use as a model. The best-known case is that of Noah Webster, who in the 19th century simplified some American spellings (color, center), and that is one of the reasons why British and American spelling do not match.

Is English the only language with this kind of spelling?

No. French also has many silent letters and Danish has a spelling far from its pronunciation. Spanish, Italian or Finnish, on the other hand, are almost phonetic.

Conclusion

To sum up in three ideas: English is not written the way it sounds because of history (the printing press fixed spelling while pronunciation was changing, the Great Vowel Shift, French and the letters added by scholars); silent letters have an explanation (lost sounds, added letters and loanwords), and almost all of them follow patterns you can learn; and many things are predictable: endings, the final «e» and double consonants.

If you want to keep going, my next suggestion is to start with the guide you find hardest in the table above. I would begin with short and long vowels.
