The schwa in English: the most common sound, weak forms and rhythm

If there is one sound that gives away a Spanish speaker speaking English, it is the schwa. It is the most frequent vowel in the language, it appears in basic words such as about, banana or teacher, and yet it does not exist in Spanish. That is why we say «a-baut» with a clear «a», and why our sentences come out with every word at the same volume, as if we were marching. You are understood, but you sound Spanish.

The good news is that the schwa is an easy sound: it is the most relaxed vowel there is. The hard part is remembering to use it. In this guide I explain what it is, how it is pronounced, in which syllables it appears, what function words and weak forms are (to, of, for, and, can…), how the schwa changes the rhythm of English, the most frequent mistakes and thirty practice sentences with answers. Let’s get started! 🙂

What the schwa (/ə/) is

The schwa is a neutral, short and relaxed vowel written with the phonetic symbol /ə/ (an upside-down «e»). The name comes from Hebrew, via German, and is pronounced /ʃwɑː/. It has three features:

• It is never stressed. It only appears in unstressed syllables. If the syllable carries the main stress of the word, it cannot be a schwa.
• It is very short. It lasts a fraction of a second, like a «uh» said almost without effort.
• It has no letter of its own. It is written with any of the five vowel letters (a, e, i, o, u), and also with combinations such as ou in famous. That is why you cannot go by how the word is spelt.

It is also the most frequent sound in English. If you master it, the pronunciation of a huge number of words improves at once, and above all the rhythm of your sentences.

How to pronounce the schwa

To produce the schwa, relax everything. It is the resting position of the mouth:

A good test: say «uh», as you do when you hesitate («uh… I don’t know»). That is, almost exactly, a schwa. With the word about, start with that «uh» and then go up to bout: uh-BOUT.

The schwa and the vowel in «cup» (/ʌ/)

Many people confuse the schwa /ə/ with the vowel in cup, but, sun, which is /ʌ/. They are similar, but not the same: /ʌ/ is slightly more open and only appears in stressed syllables, while /ə/ only appears in unstressed ones. You can see it in above /əˈbʌv/ and another /əˈnʌðə/: the first vowel is a schwa (unstressed) and the next one is /ʌ/ (stressed).

Where the schwa appears

The schwa is the form that almost any vowel takes when it is in an unstressed syllable. In this table, always look at the unstressed syllable (the one without the ˈ mark in front) and compare it with the spelling:

Notice that the a in about, the o in today and the u in support sound the same: all three are /ə/. And that the endings -er, -or, -ar are also a schwa, and the final r is not pronounced in British English.

The schwa in British and American English

There is one difference in the final schwa. In British English (the one we use on this website) the final r is not pronounced: teacher is /ˈtiːtʃə/. In American English the r is pronounced, and the final schwa takes on that sound: teacher sounds like /ˈtiːtʃɚ/. Everything else (about, banana, today) is the same in both accents.

The key: stressed and unstressed syllables

The schwa only lives in unstressed syllables. That is why, if the stress of a word changes, the schwas change as well. Look at this family of words:

As soon as you know where the stress falls, you know that all the other weak vowels are candidates for a schwa. That is why learning the stress of each word and learning the schwa go hand in hand. When in doubt, look at the transcription in the dictionary.

Function words and weak forms

This is the most practical part of the guide. In English there are two kinds of words:

• Content words: the ones that carry the meaning. Nouns, main verbs, adjectives, adverbs, negatives (don’t) and question words. They are pronounced clearly and with stress.
• Function words: the ones used to build the sentence. Articles, prepositions, pronouns, auxiliary verbs and conjunctions. They are almost always pronounced reduced, with a schwa.

Each function word has two forms: the strong one (when it is pronounced clearly) and the weak one (when it is reduced). In normal speech we use the weak one. The most important ones:

When the strong form is used

The strong form is used in three cases:

• At the end of the sentence, when the word is left on its own: Yes, I can. /ˈjes aɪ ˈkæn/ (but I can swim /aɪ kən ˈswɪm/). And Where are you from? /ˈweər ə jə ˈfrɒm/ (but I’m from Spain /aɪm frəm ˈspeɪn/).
• When you want to emphasise it or contrast it: I said from London, not to London.
• When you name the word itself: The word «of» is very common.

A very important detail: in British English, can and can’t are told apart mostly by the vowel, because the final t is barely heard. I can swim is /aɪ kən ˈswɪm/ (with a very short schwa) and I can’t swim is /aɪ ˈkɑːnt ˈswɪm/ (with a long, stressed vowel). If you always say /kæn/, your listener will not know whether you are saying yes or no.

English rhythm: why schwas change everything

Schwas and weak forms are not a detail: they are the reason English sounds the way it does. It works like this:

• Spanish is a syllable-timed language: it tends to give every syllable a similar length. That is why it sounds «even».
• English is a stress-timed language: stressed syllables come at more or less regular intervals, and unstressed syllables are squeezed and shortened to fit between them.

Look at these three sentences. They have a different number of words, but all three have three stressed syllables, so when you speak them they last almost the same time:

It is a tendency, not a mathematical rule, but it is the best way to understand why native speakers «swallow» words: they do not swallow them, they reduce them to get to the next stressed syllable on time. An example with a full sentence:

I want to go to the shop for a coffee and a sandwich.
/aɪ ˈwɒnt tə ˈɡəʊ tə ðə ˈʃɒp fər ə ˈkɒfi ən ə ˈsænwɪdʒ/

Five strong syllables (want, go, shop, coffee, sand-) and everything else in schwa. If you pronounce every word clearly, the sentence will come out slower, flatter and harder for your listener to follow.

Common mistakes with the schwa

Tips for practising the schwa

• Find the stress first. Before you pronounce a new word, check where the stress falls: everything else relaxes.
• Listen to the dictionary. English dictionaries (Cambridge, Oxford, Longman) have audio and a transcription for every word, including weak forms. Compare the weak form of to, of, for with the strong one.
• Tap the beat. Tap the table with your finger on each stressed syllable of a sentence and let the rest «fall» in between. Start with Dogs chase cats and make it longer.
• Do some shadowing. Listen to a short sentence from a native speaker and repeat it straight afterwards, imitating the rhythm and, above all, the syllables they reduce.
• Exaggerate the contrast. At first, make the stressed syllables longer and stronger, and the unstressed ones very weak. Then smooth it out.
• Record yourself. Compare your recording with the dictionary or with a native speaker. It is the quickest way to hear your clear «a»s.

FAQ: the schwa

What is the schwa in a nutshell?

It is the neutral vowel /ə/ used in unstressed syllables: a very short, relaxed «uh», like the first sound of about.

Why is it the most common sound in English?

Because almost all words of more than one syllable have unstressed syllables, and those syllables are reduced to a schwa. In addition, almost all function words (a, the, to, of, for, and…) use it in their weak form.

Is the schwa the same as the «u» in cup?

No. The one in cup is /ʌ/, slightly more open, and only appears in stressed syllables. The schwa /ə/ is more relaxed and only appears in unstressed syllables.

How do I know which syllable has the schwa?

First, find the syllable with the main stress: that one does not take a schwa. Among the others, the candidates are the weak vowels. The safe way is to look at the transcription in a dictionary.

Why do native speakers «swallow» vowels in chocolate or different?

Because in those words the unstressed vowel is so weak that it almost disappears: chocolate /ˈtʃɒklət/ has two syllables, different /ˈdɪfrənt/ has two, and comfortable /ˈkʌmftəbəl/ has three. That is why they sound «swallowed». If you pronounce them all, you sound fine, but slow.

Is there a schwa in Spanish?

No. In Spanish the five vowels are always pronounced clearly, stressed or not, and we have no neutral vowel. That is why it is so hard for us to reduce unstressed vowels in English.

Does the schwa sound the same in British and American English?

Almost always: about, banana, today are the same. The difference is in the final schwa with an r (teacher, doctor): in American English the r is pronounced.

Conclusion

To sum up in three ideas: the schwa /ə/ is the neutral, short vowel of unstressed syllables, and it is the most frequent sound in English; function words (to, of, for, and, can…) are almost always pronounced in their weak form, with a schwa; and that reduction is what gives English its rhythm, with some strong syllables and others squeezed in between.
