Diaeresis: where should it be used in Spanish?

You've probably wondered why some words in Spanish have two dots above the vowel U. This linguistic phenomenon is called diéresis in Spanish (diaeresis) and appears in certain words, but do you know what its function is?

What is diaeresis?

The diaeresis or dieresis in Spanish is an orthographic symbol represented by two small dots above vowels. In Spanish, this symbol is placed above a single vowel, the U, and only in certain words. The diaeresis indicates that the vowel is pronounced in that word.

Why then in Spanish is it only used on the vowel U? Because generally, in words such as guerra (war) or guitarra (guitar), the U is silent. In this way, the diaeresis indicates that in a specific word, the vowel is pronounced and has an independent sound.

For example, some words with diaereses in Spanish are:

• Pingüino (Penguin)
• Lingüístico (Linguistic)
• Vergüenza (Embarrassment)
• Ambigüedad (Ambiguity)
• Bilingüe (Bilingual)
• Antigüedad (Antiquity)
• Cigüeña (Stork)
• Paragüero (Umbrella stand)
• Amortigüé (Cushioned)

Without the Spanish diaeresis, the above words would be pronounced incorrectly according to the phonetic rules of the Spanish language.a

When should you use words with diaeresis?

As you have seen, the diaeresis in Spanish is used in the syllables “gue” and “gui,” where the U changes from being silent to being pronounced. Thus, this symbol ensures correct pronunciation and helps to differentiate words phonetically.

For example, in the word guerra, the U is not pronounced because the emphasis of the pronunciation falls on the vowel E. Whereas in the word paragüero, the U is pronounced so that, phonetically, the vowel sounds.

Tips for using the diaeresis

As with any other orthographic symbol, the diaeresis in Spanish has a series of rules that can help you understand it better and know how and when to use it.

• It always goes on the U. The only vowel that takes the diaeresis in Spanish is the U.
• It always goes in the syllables gue/gui. The diaeresis is only used in the syllables gue and gui so that the U in between is pronounced.
• It is always followed by vowels (e/i). Like the syllable, the U with a diaeresis is always followed by the vowels E or I.
• It is always written. The diaeresis is always written in Spanish as it indicates differences in the pronunciation of words.
• It is normally used in stressed syllables, although there are exceptions.

Diaeresis in other languages

In addition to Spanish, diaeresis are used in other languages, but with different functions. As we have seen, in Spanish diaeresis are always used to indicate that the vowel U is pronounced differently; for example, in the words pingüino (penguin) or paragüero (umbrella stand).

In other languages, such as German, the diaeresis is called an umlaut and changes the tone of the vowels ä, ö, and ü. In French, the tréma indicates that two vowels should be pronounced in separate syllables. As in French, the diaeresis has the same function in Dutch.

In English, it is very rare, appearing mainly in words from other languages or in proper names. For example, the Brontë sisters, who were writers. Other languages in which the diaeresis is present are Turkish, Finnish, and Albanian.
