Do capital letters take an accent? The myth the RAE has been debunking for decades

“Capital letters do not take an accent.” You have almost certainly heard that, perhaps from a teacher, perhaps from a relative who was absolutely sure. It is one of the most widespread spelling myths in Spanish… and it is false. Officially, it always has been: the RAE has never said otherwise. Let’s look at what the rule actually says, where the confusion came from, and which exceptions truly exist.

The rule, with no hedging

Capital letters take an accent mark (tilde) in exactly the same cases as lowercase letters. If a word is written with a graphic accent, it keeps that accent regardless of how it is capitalized:

• Álvaro, África, Él llegó tarde.
• MÉXICO, PERÚ, ÚLTIMA HORA.
• BÚSQUEDA AVANZADA, CAFÉ CON LECHE.

The RAE is blunt on this point: writing “AFRICA” or “Oscar” (when the name is Óscar) is a spelling mistake, just as incorrect as writing “africa” in lowercase. The accentuation rules — which you can review in our guide to the general rules — do not distinguish between uppercase and lowercase.

The same applies to the diaeresis (“PINGÜINO”) and to the letter eñe (“AÑO”, never “ANO”, which besides being an error can create a serious problem of meaning).

So where did the myth come from?

The myth has a fairly reasonable historical explanation: a technical limitation.

In the age of typewriters, placing an accent over a capital letter was mechanically awkward: the uppercase type occupied the full available height, and the accent mark either did not fit or sat badly. Printing presses had a similar problem with certain type sets. Faced with that difficulty, omitting the accent on capitals was tolerated as the lesser evil.

From that technical tolerance grew the legend that it was the rule. But the RAE always treated it as what it was: a limitation of the tools, not an orthographic rule. With today’s technology, where any keyboard and any font can accent capitals without effort, the excuse has disappeared completely.

The only real exceptions

Is there any case in which a capital letter is not accented? Yes, but they are very specific and have nothing to do with the general rule:

1. Acronyms written as initials (siglas). They are written without an accent even if one of their letters coincides with a stressed vowel: CIA (not “CÍA”), OTAN. Note: this applies to pure initials. Acronyms that already function as words and are written in lowercase follow the normal rules: “láser”, “módem”.

2. Unadapted foreign proper names. They are written as in their original language: Washington, München. If the name has been adapted into Spanish, it is accented according to Spanish rules: Múnich, París, Berlín.

And that is all. There are no further exceptions.

How to type capital letters with an accent on your keyboard

Part of the myth survives because many people do not know how to type them. It is easy:

• On Windows and Mac: first press the accent key (´) and then the uppercase vowel (with Shift held or Caps Lock on). It works the same way as with lowercase letters.
• On a phone: press and hold the vowel on the touch keyboard and slide to the accented version. With Caps Lock on, you will see Á, É, Í, Ó, Ú.
• Universal trick: if all else fails, type the word in lowercase with its accent and use your text editor’s “convert to uppercase” function, which preserves the accents.

In short

The next time someone tells you that capital letters do not take an accent, you already have the full answer: it was never a rule; it was a typewriter limitation that turned into an urban legend.
