Spanish Stress and Accent Marks

If you are not sure which syllable to stress in Spanish or when to use an accent mark (´), the good news is that Spanish stress follows clear rules.

This guide explains the Spanish stress rules from A1 to B1: how to find the stressed syllable, when a written accent is needed, why accents appear in verb forms such as habló, and why adding pronouns can create forms such as dámelo or explícaselo.

You do not need to learn everything at once. A1 learners only need the basic stress rules. The A2 and B1 sections explain the additional patterns as they become useful.

Spanish stress is quite predictable. If a word has no written accent mark (´), its spelling usually tells you which syllable is stressed.

A written accent mark, such as á, é, í, ó, ú, often appears when the normal stress rules would otherwise give the word a different pronunciation.

You do not need to learn every accent rule at once. Start with the A1 rules, then add the A2 and B1 patterns as you meet them.

A1 — Learn the basic stress rules

At A1, focus on one question:

If there is no accent mark, which syllable should I stress?

Rule 1: Words ending in a vowel, -n, or -s

If a word ends in a vowel, -n, or -s, the stress normally falls on the second-to-last syllable.

ca-sa — casa
ha-blan — hablan
jo-ven — joven
me-sas — mesas

Rule 2: Words ending in other consonants

If a word ends in a consonant other than -n or -s, the stress normally falls on the last syllable.

ho-tel — hotel
co-mer — comer
ciu-dad — ciudad
espa-ñol — español

Rule 3: An accent mark shows you the stressed syllable

When a word has a written accent mark, stress that syllable.

ca-fé — café
fá-cil — fácil
te-lé-fo-no — teléfono
tam-bién — también

Compare:

ha-blo — hablo
ha-bló — habló

The accent mark changes where the stress falls.

A1 quick rule

For now, remember:

vowel, -n, -s → second-to-last syllable
other consonant → last syllable
accent mark → stress the marked vowel

If you are an A1 learner, you can stop here. These rules are enough to correctly predict the stress of a large number of Spanish words.

The sections below explain why accent marks sometimes appear when words change form. You can come back to them later.

A2 — Stress can change meaning

At A2, the most important thing to understand is that stress matters in Spanish because it can change the meaning of a word or verb form.

Compare:

hablo — HA-blo — I speak
habló — ha-BLÓ — he / she spoke

The only written difference is the accent mark, but the pronunciation and meaning are different.

You will often see this in verb conjugations:

hablo — I speak → habló — he / she spoke
trabajo — I work → trabajó — he / she worked
termino — I finish → terminó — he / she finished

You will also see accents in common past-tense forms such as:

hablé
comí
viví
comió
vivió

A2 quick rule

Pay attention to accent marks when learning verb forms. They show you where the stress goes, and changing the stress can change the meaning.

You do not need to analyze why every accent appears yet. Learn it as part of the verb form.

B1 — Keeping the stress when pronouns are added

At B1, accent marks become especially important when object or reflexive pronouns are attached to a verb.

This happens frequently with:

infinitives
gerunds
affirmative commands

The basic principle is still the same:

When pronouns are attached, the word becomes longer. A written accent may be needed so that the original stress does not move.

Infinitive + pronoun

Compare:

decir → decirlo
explicar → explicarlo

These forms do not need a written accent because the normal stress rules already put the stress in the correct place.

But with two pronouns:

decir → decírmelo
explicar → explicárselo

The added syllables would change the default stress pattern, so an accent is needed to preserve the original stress.

de-cír-me-lo
ex-pli-cár-se-lo

Gerund + pronoun

The same principle applies to gerunds.

diciendo → diciéndolo
explicando → explicándome
dando → dándoselo

The pronouns make the word longer, but the original stressed syllable remains stressed. The accent mark makes that clear.

Affirmative commands + pronouns

Affirmative commands can also have pronouns attached to the end:

dime — tell me
hazlo — do it
dámelo — give it to me
explícamelo — explain it to me
díselo — tell it to him / her / them

Look at:

da → dame → dámelo

The stress stays on da.

Once me and lo are attached, however, damelo would follow the normal stress rule and be pronounced differently. The written accent in dámelo preserves the intended stress:

DÁ-me-lo

Another example:

di → dile → díselo

The accent in díselo keeps the stress on di.

This is why forms such as dámelo, díselo, and explícaselo have accent marks. They are not arbitrary exceptions: they follow the normal Spanish stress system.

A useful way to think about accent marks

Instead of memorizing every accented form separately, think in this order:

Where is the word supposed to be stressed?
Where would the normal Spanish stress rules put the stress?
If those are different, a written accent mark may be needed.

For example:

dámelo

Without an accent:

damelo → the normal rule would stress me, because the word ends in a vowel.

But the command keeps the stress on da:

DÁ-me-lo

Therefore:

dámelo

This same principle explains many accent marks that appear when Spanish verbs change form or when pronouns are attached.

What should you learn at each level?

A1

Learn these rules well:

vowel, -n, or -s → stress the second-to-last syllable;
other consonants → stress the last syllable;
a written accent mark tells you which syllable is stressed.

That is enough for now.

A2

Add:

common verb forms can contain written accents;
accents such as hablé, comió, and habló are part of the correct conjugation;
an accent can distinguish forms such as hablo and habló.

You should recognize these patterns, but you do not need to analyze every accent mark you see.

B1

Learn how the basic stress rules explain accents when pronouns are attached:

decírmelo
diciéndolo
dámelo
díselo
explícaselo

At this level, it is useful to understand why the accent appears instead of memorizing every form individually.

Quick rule

The most important idea is simple:

Spanish has predictable default stress. Written accent marks are used when the required stress does not follow that default pattern.

For beginners:

Learn the default stress rules first. Everything else will make much more sense later.
