Common Mistakes Native Spanish Speakers Make

Even native speakers make mistakes in Spanish. Learn the most common errors, redundancies, and grammar slip-ups you'll hear in real life — and how to sound more natural.

Even native Spanish speakers make mistakes. A lot of them. You'll hear these every day in Mexico, in Latin America, and on Spanish TV — even from teachers, journalists, and your in-laws.

Spoken language and formal grammar are often very different. Many expressions become so common that, even when they're technically wrong, almost everyone says them. Learning to spot these mistakes will help you:

• Sound more natural when you speak • Understand what natives actually say (not just textbook Spanish) • Avoid the slip-ups that make written Spanish look unpolished • Know when a 'mistake' is acceptable in casual speech and when it isn't

**Heads up:** Many of these mistakes are extremely common in **Mexico** and across **Latin America**. Hearing them does not mean the speaker is uneducated — it means the language is alive.

Section 1 — Redundancies (Pleonasms):

A pleonasm is when you use extra words that repeat the same idea. Spanish is full of them, especially in spoken form.

❌ Incorrect✅ CorrectWhy it's wrongExample
Pero sin embargo**Pero** / **Sin embargo**Both mean *however* — pick onePero sin embargo no vino. → *Sin embargo, no vino.*
En base en**Con base en** / **Basado en**Wrong prepositionEn base en los datos… → *Con base en los datos…*
Subir para arriba**Subir**Subir already means *to go up*Sube para arriba. → *Sube.*
Bajar para abajo**Bajar**Bajar already means *to go down*Baja para abajo. → *Baja.*
Entrar adentro**Entrar**Entrar already means *to go inside*Entra adentro. → *Entra.*
Salir afuera**Salir**Salir already means *to go out*Sal afuera. → *Sal.*
Más mejor**Mejor***Mejor* is already a comparativeEs más mejor. → *Es mejor.*
Más peor**Peor***Peor* is already a comparativeEs más peor. → *Es peor.*
1

**Cultural note:** You'll still hear *'súbete para arriba'* and *'sal para afuera'* from grandmothers across Mexico. In casual speech nobody will correct you — but **never** write them in a school essay or work email.

Section 2 — Verb Mistakes:

These verb forms are very common in informal or low-formality contexts — but they are not considered correct standard Spanish.

❌ Incorrect✅ CorrectTense / explanationPronunciation tip
Haiga**Haya**Present subjunctive of *haber* — *haiga* is archaic / non-standardSoft 'y' sound: *AH-yah*
Veniste**Viniste**Preterite of *venir* — stem changes to *vin-**bee-NEES-teh*, not *beh-*
Dijistes**Dijiste**Preterite *tú* form — never ends in *-stes*One *-s* only at the end
Andé**Anduve***Andar* is irregular in the preterite*an-DOO-beh*
Cabo**Quepo***Caber* (yo form, present) — *yo quepo*, not *yo cabo**KEH-poh*
Satisfació**Satisfizo***Satisfacer* conjugates like *hacer**sah-tees-FEE-soh*
1

**Note:** These mistakes are linked to **informal speech** and certain regional accents. Native speakers usually know the correct form exists — they just don't use it day-to-day.

Section 3 — Hay vs Ahí vs Ay:

Three tiny words that sound almost identical but mean completely different things. Even natives mix them up in writing.

WordMeaningExample
**Hay***There is / there are* (verb *haber*)**Hay** tres tacos en el plato.
**Ahí***There* (location)El libro está **ahí**.
**Ay***Ouch! / Oh!* (interjection)**¡Ay!** Me duele la cabeza.
1

**Quick Memory Tip:** *Hay* has an **H** like *have* (there is). *Ahí* points to a place (think *aquí, ahí, allí*). *Ay* is the shortest — just a sound of **pain or surprise**.

Section 4 — A ver vs Haber:

Another homophone trap. They sound identical but do very different jobs.

FormWhat it meansUse it when…
**A ver***Let's see / let me see*You're about to look at, check, or wait for something
**Haber***To have* (auxiliary) or *there to be* (infinitive of *hay*)You're using a compound tense or speaking impersonally

Real-life examples: • A ver qué pasa. — Let's see what happens. • A ver, dame el papel. — Let me see, hand me the paper. • Debe haber comida en la nevera. — There must be food in the fridge. • Va a haber una fiesta. — There's going to be a party.

1

**Quick check:** If you can replace it with *'let's see'* → it's **a ver**. If it follows a verb like *debe*, *va a*, *puede* → it's **haber**.

Section 5 — Había vs Habían / Hubo vs Hubieron:

When haber means 'there is / there are / there was / there were', it is impersonal. That means it does NOT change for plural. Most natives get this wrong.

❌ Incorrect✅ CorrectEnglish
Habían muchas personas.**Había** muchas personas.There were many people.
Hubieron problemas.**Hubo** problemas.There were problems.
Habrán fiestas.**Habrá** fiestas.There will be parties.
Han habido cambios.**Ha habido** cambios.There have been changes.

Grammar note: Haber used as 'there is/are' is an impersonal verb — it has no subject, so it always stays in the third-person singular. The number of things that exist does not matter.

1

You'll hear *'habían muchas personas'* from politicians on national TV. It is still considered incorrect in formal grammar.

Section 6 — Dequeísmo & Queísmo:

These are two opposite errors — one adds de where it doesn't belong, the other removes it where it does.

ErrorDefinition❌ Wrong✅ Right
**Dequeísmo**Adding *de* before *que* when you shouldn'tPienso **de que** vendrá.Pienso **que** vendrá.
**Dequeísmo**Same — with another verbCreo **de que** es tarde.Creo **que** es tarde.
**Queísmo**Removing *de* when you should keep itMe alegro **que** vengas.Me alegro **de que** vengas.
**Queísmo**Same — with *acordarse*Me acuerdo **que** llovió.Me acuerdo **de que** llovió.

Quick rule: Try replacing que… with eso. If you'd say 'pienso eso' → no de needed. If you'd say 'me alegro de eso' → keep the de.

Why do native speakers make these mistakes?

Languages are alive. They change every day. Most of these mistakes happen because of:

CauseWhat it means
**Language evolution**What's 'wrong' today may be standard in 50 years
**Regional speech**Different countries and regions normalize different forms
**Informal communication**Casual speech relaxes the rules
**Frequency & habit**If you hear it 1,000 times, it sounds right
**Prescriptive vs descriptive grammar**Textbooks describe how Spanish *should* be spoken; people speak how they actually do
