Here is audio for some of the examples in my article on this topic on Medium.


Long-U2 /uw/

  • Long-U2 is used after consonants that are made with the front part of the tongue.
  • For English, these consonants are: T / D / S / Z / L / R / TH / SH / CH / J.
    Some examples are: tube / duty / clue / suit / rule / enthused / June.
  • Sometimes this vowel sound has other spelling patterns:
    >> “EW”, “EU”: dew / chew / blew / flew / deuce / sleuth
    >> “OO”: choose / soon / zoom / shoot / loose / mood / cool

Long-U1 /yuw/

  • Long-U1 is used for all other contexts. That means after any consonant sound that is NOT made with the front part of the tongue.
  • For English, those consonants are: P / B / F / V / M / C (K) / G / H.
    Some examples are: pupil / bugle / fuel / music / cube / argue / huge.
  • In addition, “other contexts” also includes when Long-U is the first letter of a word.
    For example: use / union / unit.
  • Some alternative spellings are:
    >> “EW”, “IEW”, “EU”: few / mew / view / feud / eulogy / eucalyptus

NOTE

Words with “N” are not predictable, so they need to be learned individually. When you see a new word that has “N” before Long-U, just remember to check how to say it.

  • Some that always use Long-U1 are: annual / continue / genuine / granule / innuendo / January / manual / manufacture / menu / minuet / monument / venue. These all sound odd if they are pronounced with Long-U2.
  • Some examples with Long-U2 are: avenue / manure / nuance / nude / nucleus / numeric / new / news. (Some of these can also be pronounced with Long-U1, but that makes them sound more old-style.)

Try It!  

Using the patterns explained above, you now can figure out how the Long-U should be pronounced in these words, even if some of the words are unfamiliar for you. (You can find the answers are at the bottom of this post.)

Long-vowel IPA symbols

Knowing the Long-vowel sounds and Short-vowel sounds of English can help you be better at pronouncing new words and deciphering spelling patterns, but it also helps to be aware of the IPA (International Phonetic Alphabet) symbols for the vowels. Some people learn IPA symbols when they first begin to learn English, but others have never seen these symbols before. Either way, it can be useful to refer to them for some aspects of English pronunciation.

One of the main differences between Long and Short-vowels is that Long-vowels have two parts to their sound and Short-vowels have one part. In the Long-vowel IPA symbols below you can see the two parts for each Long-vowel.

LongV IPA

Here are two situations where it is helpful to take a look at the IPA symbols of Long-vowels.

1. Vowel sequences

A vowel sequence is when there are 2 vowels next to each other, and they both have a sound, and they belong to different syllables, as in the words “idea” (3 syllables), or “fluid” (2 syllables). (NOTE: This is different from vowel pairs that belong to the same syllable and make only one sound.)

In order to pronounce both of the vowels in a sequence clearly, so that they can both be heard clearly, we need to make special use of the second part of the first vowel. Let’s see how that works with the words “idea” and “fluid”.

Idea — In this word the first vowel of the sequence is a Long-E, and the IPA symbol (/iy/) shows a “y” at the end. The trick is to use that “y” part to separate the two vowels. This is done by pronouncing it a little bit stronger than usual. This makes the word sound like it could be spelled as “ideya”.

Fluid — In this word the first vowel is a Long-U. The IPA symbol (/uw/) shows a “w” at the end. This “w” is emphasized, to make a separation between the [u] and the [i], and it sounds like “fluwid”.

2. Consonant morphing

The consonants “T”, “D”, “C”, “S”, and “Z” sometimes change their sound. Here are some examples:

“virtue” — the “T” sounds like “CH”
“educate” — the “D” sounds like “J”
“sugar” — the “S” sounds like “SH”
“social” — the “C” sounds like “SH”

This kind of consonant change can happen when the consonant is followed by a high-front vowel sound — this is seen as either a “y” or “i” in IPA symbols. In words like these, there is (or once was) either a Long-I-2 /iy/ or a Long-U-1 /yuw/ right after the morphing consonant. The consonant combines with the high-front part of the vowel sound and changes.

In some of these words, the original vowel sound is lost. For example, in “social” the [i] is lost when it combines with the [c] (the [a] remains as schwa). However, in “educate” the [d] gets changed but the Long-U can still be heard.

SO, overall, it is most helpful to know the vowel system in terms of Long and Short-vowels, because many pronunciation patterns make use of them, but also keep your eye on the IPA symbols for extra clues.

Overview of Vowels

Do you know the total number of different vowel sounds in English?

Beginners often think the answer is “five”, because there are five vowel letters in the alphabet. Of course, anyone familiar with this blog already knows that each vowel letter has at least one Long-vowel and one Short-vowel sound. So is it ten vowels total? Nope! The answer is… fifteen different vowel sounds!

The English vowel system is complex, and almost every learner of English has trouble with at least a few of the vowels. The vowel system is the most difficult part of figuring out how to pronounce new words. So, mastering the vowel system can make a huge improvement in the way you sound in English, and it can help you be better at figuring out how to say new words.

All of the vowel sounds have been explained in other posts, so here is the complete list.

Long-U: 1 or 2?

The vowel “U” is a bit unique because it has two Long-vowel sounds. The two sounds are very similar, but they are used in different situations. So, how do you know which one to choose?

It all depends on which letter comes just before the Long-U.

Long-U-2 (/uw/)

Long-U-2 is used after sounds that are made with the front part of the tongue. This includes: T / D / L / N / S / R / TH / J. Here are some examples: tune / duty / elude / nuclear / suit / rule / enthused / June.

Long-U-1 (/yuw/)

Long-U-1 is used after any sounds that are not made with the front part of the tongue. This includes: P / B / F / M / K / G / H / “none”. Some examples are: pupil / bugle / fuse / music / cube / argue / huge / use.

Exceptions

In English there are always exceptions, and in this case the exceptions happen with some Long-U-2 words.

  • Some words with a “T” or “N” can also be pronounced with Long-U-1. Some examples — pronounced both ways — are: tune / tube / avenue / news. Now, the second way (with Long-U-1) sounds more old-fashioned, like the way some elderly people speak. So, following the rule keeps it more simple for you. But be aware that you may hear some people say a few words the other way, so don’t let it confuse you.
  • There is a handful of words with “L” and “N” that always go against the rule, and use Long-U-1. You should memorize these ones: volume / value / evaluate / menu / January / monument.

Does it really matter which one you use?

It can. Especially when you accidentally use Long-U-2 in place of Long-U-1.

  • There are some words that can be confused. For example, if you want to say the word “use” but you pronounce it with Long-U-2 instead of Long-U-1, then you will end up saying the word “ooze”. Likewise, “hue” would sound like “who”.
  • Even if there is not a word that could be confused, using the wrong sound could make you unclear. For example, if you try to say a word such as “huge” or “pupil” with the wrong sound, others may not understand what you are talking about.
  • With bigger words, other people will probably still understand you. So if you try to say “regular”, “computer” or “document” with Long-U-2 (instead of Long-U-1), it will sound like a mistake, but most of the time others will know what word you are trying to say.

Another phenomenon

There is a group of words that have a sound change when a “T” or “D” comes before a Long-U-1. For example, in a word like “actual”, the “T” gets combined with the “Y” part of Long-U-1 (/yuw/) and turns into a “CH” sound. Likewise, in “graduate” the “D” combines with the “Y” and makes a “J” sound. There are quite a few words like this, such as: statue / costume / situation / punctuate / virtual / individual / schedule.

However, this is a phenomenon that does not only happen with Long-U. These words are part of a bigger pattern, and will be the topic of a different post.

The Sounds of U

The vowel system is the most complicated part of the pronunciation-spelling system of English, because each vowel letter represents three or four different vowel sounds. The letter “U” has three different sounds, but one thing that is unique about “U” is that it has two Long-vowel sounds.

The basic sounds of the English letter “U” are: Long-U-1, Long-U-2, and Short-u.

Long-U-1

The sound of Long-U-1 is the same as the name of the letter “U”. However, this long-vowel sound is a little bit unusual because Long-vowels usually have two parts, but Long-U-1 has three parts (in IPA: /yuw/). Some common words with this sound are: use / music / huge / cute / unite / cure / menu / fuel / human / argue.

Long-U-2

The second Long-U sound is almost the same as Long-U-1, except that it has only two parts (in IPA: /uw/). Some words with this sound are: true / flute / blue / June / spruce / tune / rule / tube / duty / include.

Short-u

Short-u is pronounced in the center (not front, not back) middle (not high, not low) part of the mouth, and the tongue needs to be relaxed.  Some common words with this sound are: up / just / but / much / under / us / run / study / number / because.

Schwa

Any vowel letter can use the schwa sound in unstressed syllables. However, since the schwa sound and Short-u are both made in the same place in the mouth, they end up sounding the same. A linguist would make a distinction between Schwa and Short-u based on stress, so for example, the first letter of the word “under” would be considered a Short-u sound, but in the word “upset” the first letter would be called a Schwa. The good news for learners of English is, you can treat them as the same sound, and your English pronunciation will sound great.

So remember, it is very rare to find the letter “U” pronounced with something other than these three basic sounds. There is a handful of words with a “U” pronounced as Short-oo: sugar / put / push / puss / pull / full / bull / cushion. There are also two words with a very unusual pronunciation, “busy” and “business”. In these two words the “U” has a Short-i sound! Otherwise, when you see the letter “U” in a word, it will almost always have the sound of either Long-U-1, Long-U-2, or Short-u (Schwa).


ADDITIONAL NOTES

1. Vowel pair “OU” — Several different vowel sounds are used for the vowel pair “OU”, and it is not easy to predict. See: OU – Oh no!

2. Test yourself! — Many students have difficulty distinguishing between Short-u and Short-o. You can test yourself on the “Vowel Test” page of the PronunciationCoach site.
