Spanish Word Stress and Accent Marks

¡Hola de nuevo! Last time, you practised the strong back-of-the-mouth sound written j and g before e or i, as in jardín, gente, and elegir. Clear consonants matter, but so does giving the right syllable prominence: jardín and jardín are not interchangeable pronunciations.

In this lesson, you will learn the compact system Spanish uses to signal word stress. By the end, you should be able to look at an unfamiliar written word, locate its stressed syllable, and understand when a written accent mark, or tilde, is required. This is especially useful for reading aloud and for storing new vocabulary accurately from the beginning.

1. Stress first, then the spelling rule

Every Spanish word has a stressed syllable: the syllable pronounced with slightly greater prominence. It is often a little longer, clearer, or marked by a small pitch movement. In these examples, capital letters show the stressed syllable:

• CA-sa
• es-PA-ña
• pa-RED
• te-LÉ-fo-no

A written accent such as á, é, í, ó, ú is called an acento or, in everyday usage, a tilde. Its most important reading rule is absolute:

If a word has a written accent, stress the syllable containing it.

So you do not need to calculate anything for:

• canCIÓN
• jarDÍN
• ÁRbol
• teLÉfono
• MÉdico

When there is no written accent, use the word’s final letter:

1. If the word ends in a vowel, n, or s, stress the second-to-last syllable.
2. If it ends in any other consonant, stress the last syllable.

This pair of defaults lets you pronounce a great many unfamiliar words confidently:

Word	Ending	Default stress	Pronunciation guide
casa	vowel	second-to-last	CA-sa
gente	vowel	second-to-last	GEN-te
joven	n	second-to-last	JO-ven
lunes	s	second-to-last	LU-nes
hablar	r	last	ha-BLAR
reloj	j	last	re-LOJ
universidad	d	last	u-ni-ver-si-DAD

The final letter is not telling you what the word means. It is simply giving you the default stress location.

The Spanish Word-Stress Rules graphic groups words into traditional names. These names are useful, but the two default patterns above are the engine that makes the system work.

2. Why some stressed words need an accent mark

A common beginner confusion is this: stress and written accents are not the same thing.

Every multi-syllable Spanish word has stress. A written accent appears only when the pronunciation does not follow the normal final-letter pattern, or when it serves another special function.

Final stress: palabras agudas

Words stressed on the last syllable are called agudas.

• If an aguda ends in a consonant other than n or s, it follows the normal pattern and has no accent: hotel, hablar, reloj, pared.
• If it ends in a vowel, n, or s, it needs an accent to show the unexpected final stress: café, corazón, canción, inglés.

Compare:

• JO-ven ends in n, so its normal stress is second-to-last.
• jar-DÍN also ends in n, but its stress is final. The í must be written to override the default.

Second-to-last stress: palabras llanas or graves

Words stressed on the second-to-last syllable are called llanas or graves.

• If they end in a vowel, n, or s, this is normal and there is no accent: casa, domingo, joven, personas.
• If they end in another consonant, they need an accent: árbol, fácil, carácter, azúcar.

Compare:

• re-LOJ ends in j, so final stress is normal.
• LÁ-piz ends in z, so final stress would be expected. The accent tells you to stress the first syllable instead.

Third-to-last stress: palabras esdrújulas

If the stress is on the third-to-last syllable, the word is an esdrújula. These always carry a written accent.

• MÉ-di-co
• te-LÉ-fo-no
• PE-lí-cu-la
• RÁ-pi-do

Words stressed even farther from the end are sobresdrújulas, and they also always have an accent: CÓM-pra-me-lo, DÍ-me-lo. You will meet more of these later when working with verbs and pronouns.

Here is the complete core pattern in one table:

Stress location	Traditional category	When is an accent written?	Examples
Last syllable	aguda	When the word ends in a vowel, n, or s	café, jardín, canción
Second-to-last	llana / grave	When the word ends in a consonant other than n or s	árbol, fácil, lápiz
Third-to-last	esdrújula	Always	médico, teléfono
Before the third-to-last	sobresdrújula	Always	dímelo, cómpramelo

3. A reliable method for reading unfamiliar words

Use this short routine whenever you encounter a new written Spanish word.

Step 1: Look for an accent mark

If you see á, é, í, ó, or ú, stress that syllable.

• tamBIÉN
• difÍcil
• desPUÉS
• MÁquina

Step 2: If there is no accent, divide the word into syllables

You do not need perfect grammatical analysis. A practical spoken division is enough:

• ven-ta-na
• com-pu-ta-do-ra
• u-ni-ver-si-dad
• es-pe-rar

Step 3: Check the final letter

• Ending in vowel, n, or s: stress the second-to-last syllable.
• Ending in another consonant: stress the last syllable.

Read this set aloud in two rounds. On the first round, pause and identify the final letter. On the second, say each word naturally with the marked stress.

ven-TA-na
com-pu-ta-DO-ra
es-PE-ran
u-ni-ver-si-DAD
ha-BLAR
re-LOJ
GEN-te
JO-ven

Now use the written accents as direct instructions:

jar-DÍN
can-CIÓN
ÁR-bol
LÁ-piz
te-LÉ-fo-no
MÉ-di-co

Notice how this connects to the previous pronunciation lessons:

El te-LÉ-fo-no está en el jar-DÍN.
La GEN-te JO-ven quiere via-JAR.

Keep the consonants you have learned clear, especially the Spanish j sound in jardín and viajar, but let the stressed syllable organize the rhythm of the whole word.

From pronunciation to correct spelling

When you already know how a word is pronounced and want to write it, reverse the process:

1. Divide it into syllables and identify the stressed one.
2. Check whether that stress matches the default implied by the final letter.
3. If it does not match, write an accent on the stressed vowel.
4. If it is third-to-last or earlier, write an accent.

For example, you hear can-CIÓN. Since it ends in n, the normal pattern would be CAN-cion. To preserve final stress, you write canción.

You hear ÁR-bol. Since it ends in l, normal stress would be final. To preserve second-to-last stress, you write árbol.

One useful refinement: the simplified “ends in s” rule normally refers to a single final s. Words ending in a consonant group such as bíceps need an accent for second-to-last stress. This is an occasional edge case; for now, rely on the core rule for the overwhelming majority of everyday vocabulary.

4. Two important limits of the stress rule

The stress system is regular, but written accents sometimes do work other than changing the stress pattern.

One-syllable words

A one-syllable word has no competing syllables, so it usually has no written accent: sol, pan, fui, fue. But a tilde can distinguish two words with different meanings:

With tilde	Meaning	Without tilde	Meaning
él	he	el	the
tú	you	tu	your
té	tea	te	you, as an object pronoun
más	more	mas	but

These accent marks generally do not change pronunciation. They help the reader identify the intended word.

Question and exclamation words

Words such as qué, cómo, cuándo, and dónde receive accents in questions and exclamations:

• ¿Qué quieres hacer?
• ¿Cómo estás?
• No sé cuándo llega.

Without the accent, the same spellings can have other grammatical roles:

• como = as, like, or “I eat”
• cuando = when
• donde = where
• que = that, which

For cómo and como, the stress is normally still on the first syllable: CÓ-mo. The written accent is primarily distinguishing meaning and grammatical use.

Finally, when an accent appears on í or ú next to another vowel, pronounce that weak vowel clearly as its own syllable:

• pa-ÍS
• Ma-RÍ-a
• dí-a
• ba-ÚL

For now, treat this as a reading signal: an accented í or ú beside a vowel deserves special attention.

Key takeaways

Spanish spelling gives you a practical pronunciation system:

• A written accent always identifies the stressed syllable.
• With no accent, words ending in a vowel, n, or s are normally stressed on the second-to-last syllable.
• Words ending in other consonants are normally stressed on the last syllable.
• Agudas need an accent when final stress conflicts with the vowel-n-s default.
• Llanas or graves need an accent when second-to-last stress conflicts with the other-consonant default.
• Esdrújulas and sobresdrújulas always have an accent.
• Some accents distinguish meanings rather than changing pronunciation, especially in one-syllable and question words.

As you learn vocabulary, say the stressed syllable aloud and copy any accent mark as part of the word’s spelling. Next, you will add practical conversation-control phrases for gaining time, asking someone to repeat something, and correcting yourself without losing the flow of a conversation.
