Written Accent Marks

Italian uses two written accent marks — the grave (à, è, ì, ò, ù) and the acute (é, very rarely ó) — to mark final-syllable stress in multisyllabic words and to disambiguate a small set of monosyllables. The system is small but every learner — and many native speakers — get some part of it wrong. Writing perchè with a grave is a real spelling error: the word is perché with an acute. Writing e without the accent for the verb form è changes "is" into the conjunction "and" and produces an ungrammatical sentence.

This page covers what to write: which accent goes where, when it's mandatory, when it's wrong, and the famous trio of traps that show up in every Italian spelling test (perché, po', qual è). For the underlying pronunciation logic — why the grave marks open è and the acute marks closed é — see Accent Marks: Grave and Acute. Here, the focus is the writing convention.

1. When the accent is mandatory

Italian writes the accent in two situations and only two:

1. Final-syllable stress in multisyllabic words. Città (cit-TÀ), caffè (caf-FÈ), perché (per-CHÉ), partì (par-TÌ). Without the accent, the spelling would default to penultimate stress and produce the wrong reading. The accent is obligatory — citta without the accent is a spelling error.
2. Disambiguation of a small set of monosyllables. È (is) vs e (and), sì (yes) vs si (reflexive), là (there) vs la (the/her), dà (gives) vs da (from), and a few more. These are one-syllable words where stress isn't really at issue, but the accent distinguishes the meaning in writing.

Outside these two situations, Italian does not write accents. Words stressed on the penultimate syllable (the default) get no mark; words stressed on the antepenultimate syllable (telefono, abito, parlano) also get no mark and have to be learned by ear.

2. The grave accent — the default for final stress

The grave accent (à, è, ì, ò, ù) is the default for final-stressed multisyllabic words. The vast majority of final-stressed words take grave.

The grave is also used on verb forms with final stress — particularly third-person singular forms in the passato remoto (parlò, comprò, andò) and the future (sarà, andrà, parlerà). The accent is mandatory in all of these.

3. The acute accent — almost exclusively -ché words

The acute accent (é) is reserved for a small, well-defined set of words. The vast majority of acute-accent words end in -ché — that is, they consist of some prefix or element plus the conjunction che, fused into a single word with final closed e.

The closed e in this set is etymologically consistent — it descends from the Latin quid via Vulgar Latin pronunciations that preserved the closed quality. That's why all -ché words take the acute, while cioè (that is, in other words) takes the grave: cioè ends in open è, not closed é.

A few standalone words with acute

Outside the -ché family, only a small number of words take the acute:

That's effectively the entire acute-accent inventory for stressed final vowels in standard Italian. Everything else uses the grave.

Why so few acute accents?

The reason there are so few words with acute é (and almost none with acute ó) is that stressed final closed e and o are rare in Italian. The -ché family inherits its closed e from etymology; the -tré numerals work the same way. Outside these specific etymological pockets, final stressed e and o tend to be open and take the grave.

A handful of dictionary-marked words use acute ó for closed o (like bótte "barrel" vs bòtte "blows"), but in normal text these distinctions are not written. The acute é of perché and the standalone words above is the only acute you reliably encounter in everyday Italian.

4. Monosyllable disambiguation — the same-spelled, different-meaning pairs

Italian has a small set of one-syllable words that take an accent not because of stress (a monosyllable's stress isn't ambiguous) but to distinguish them from identically-spelled but grammatically different words. This is purely an orthographic convention.

The pattern: the accented form is the one most learners get wrong. Italian grammar is unforgiving here — e without an accent really is a different word from è with one, and the spelling rule is non-negotiable. Software autocorrect frequently fails to add these accents, so getting them right is a sign of careful Italian writing.

The choice of grave vs acute on monosyllables

Most disambiguating monosyllables take the grave (è, sì, là, lì, dà, dì, tè). Three take the acute: né, sé, ché. The pattern follows the open/closed distinction:

• è (is) — open /ɛ/ → grave
• né (nor) — closed /e/ → acute
• sé (oneself) — closed /e/ → acute
• ché (because, poetic) — closed /e/ → acute (same as the full form perché)
• tè (tea) — open /ɛ/ → grave

For the most part you don't need to think about it — these are fixed orthographic conventions. Just memorize which word takes which mark.

Monosyllables that do NOT take an accent

A common over-correction is to add accents to monosyllables that don't need them. The following are unaccented in modern Italian:

The bare tre (three) does not take an accent — it's monosyllabic and unambiguous. But the multisyllabic compounds ventitré, trentatré, quarantatré etc. do take the acute, because they end in a final-stressed multisyllabic word.

5. The three famous traps

Every Italian schoolchild learns three specific orthographic mistakes that show up on every spelling test. Mastering these three is the difference between native-looking writing and visibly non-native (or careless) writing.

Trap 1: perché with grave instead of acute

The single most common Italian spelling error — even among native speakers in informal contexts — is writing perché with a grave accent (perchè). It's so widespread that you'll see it on signs, in social media posts, even in older newspaper texts. But the standard, the dictionaries, and every Italian grammar agree: perché has the acute accent. Writing perchè is a spelling error.

The reason it matters: the grave/acute distinction in Italian encodes the open/closed vowel quality. Perché ends in /ke/ (closed e), so the acute is correct. Writing perchè would imply /kɛ/ (open e), which would be a different pronunciation. Even though many Italians don't actually distinguish these vowels in speech, the spelling rule is fixed.

The same applies to the entire -ché family: poiché, affinché, benché, finché, sicché, giacché, dacché, acciocché. All take acute. Writing any of them with grave is wrong.

Trap 2: po' with apostrophe — NOT pò with accent

The word po' (meaning "a little") is written with an apostrophe, not an accent. It is a truncated form of poco — the final -co has been dropped, and the apostrophe records that truncation. It is not pò with a grave accent.

The reasoning: a written accent marks final-syllable stress and (for e/o) vowel quality. But po' is not a stressed final vowel of a longer word — it's an apocopation, a truncation, of poco. The apostrophe records the missing letters; an accent would be inappropriate.

For more on the apostrophe and apocope, see The Apostrophe in Elisions.

Trap 3: qual è with no mark — NOT qual'è

The question phrase "qual è...?" ("which is...?", "what is...?") is written without any apostrophe, even though qual ends in a consonant cluster that looks like it should be elided before è. The form qual is an apocopation of quale — the final -e of quale has been dropped, but the dropping happened in advance, lexicalized into a separate form. There's no live elision happening at the qual / è boundary, so no apostrophe is written.

The same applies to qual in any combination: qual è, qual era, qual altro, qual altra, qual sia. Always two words, no apostrophe.

6. Why does Italian mark stress at all?

Italian's accent-mark system is much more limited than Spanish's. Spanish marks every non-default stress with a written accent: teléfono, música, cárcel, así, también. Italian marks only final-syllable stress of multisyllabic words plus the small set of disambiguating monosyllables.

The reason is historical: the modern Italian accent system was codified to resolve genuine ambiguities, not to teach pronunciation. The cases where Italian writes the accent are exactly the cases where the spelling would otherwise mislead — citta would default to penultimate stress (CIT-ta or cit-TÁ?), so the accent forces the correct cit-TÀ. Similarly, e "and" and è "is" need to be visibly distinguished.

Words like telefono, abito, parlano do not receive accent marks even though they break the penultimate default, because the system was not designed to teach speakers where the stress falls — it was designed to record what speakers already know. This is why Italian dictionaries use additional internal accent marks (tÉ-le-fo-no, PAR-la-no) that are absent in normal text.

For where the stress actually falls in unmarked words, see Word Stress Rules.

7. Quick reference: when to write what

8. A typing note: how to enter Italian accents

On most keyboards, getting Italian accents requires either an Italian keyboard layout (which has dedicated keys for à è é ì ò ù) or specific keystroke combinations. The most common methods:

• Italian keyboard layout: dedicated keys to the right of the letter row. à is shift-something on most layouts.
• US keyboard with international shift: hold the option key and press the corresponding character (Mac) or use ASCII codes (Windows).
• Mobile: long-press the vowel to get a menu of accented variants. à è é ì ò ù are all available this way.
• Word processors: most autocorrect e' / a' into è / à automatically. Watch out — this autocorrect often produces grave (è) when acute (é) is needed for perché.

Native Italians and careful typists pay attention; learners who copy-paste Italian text from outside sources should double-check that perché really has acute and not grave.

Common Mistakes

Key takeaways

• Italian uses two accent marks: the grave (à, è, ì, ò, ù) and the acute (é, very rarely ó).
• Accents are written only on stressed final vowels of multisyllabic words, plus a small set of monosyllables for disambiguation.
• The grave is the default: città, caffè, però, virtù, lunedì. Most final-stressed words take grave.
• The acute is reserved for closed e: almost exclusively -ché words (perché, poiché, affinché, benché, finché, sicché, giacché, dacché, acciocché) plus né, sé, and the -tré numerals (ventitré, trentatré, etc.).
• A small set of monosyllables take an accent purely for disambiguation: è/e, sì/si, né/ne, sé/se, là/la, lì/li, dà/da, dì/di, tè/te, ché/che.
• The three famous traps every Italian schoolchild learns: (1) perché with acute, never perchè with grave; (2) po' with apostrophe, never pò with accent; (3) qual è with no mark, never qual'è with apostrophe.
• The apostrophe and the accent are different marks with different functions and are never interchangeable.
