EVERY Expression with ‘mero’ in Mexican Spanish

If you say ‘mero’ in most Spanish-speaking countries, people will probably assume that you’re after fish, more specifically a ‘grouper’ (which is super yummy by the way!).

But in Mexico they definitely WON’T

… and, well, that’s because Mexicans use the word ‘mero’ colloquially in a dazzling array of different phrases / expressions.

A little bit of background: the word ‘mero’ actually comes from the Latin ‘merus’ meaning ‘pure’ or ‘simple’ (yep, like the English word ‘mere’).

Ironically, things aren’t so “simple”when it comes to expressions with ‘mero’, with meanings ranging from ‘insignificant’ to ‘the very best’!

Let’s get into the nitty-gritty!

What part of speech is ‘mero’?

Well, it can actually be an adjective AND an adverb (uh-oh!).

I’m nothing more than a mere intermediary.



Mero’ as an adverb

Now let’s explore the various uses of this super useful Mexican word!


Used to describe “oneself


1 Yo mero – Myself

If you wanna say ‘myself’ in Spanish, you’d say ‘yo mismo’ or ‘mí mismo’.

The same goes with the rest of the pronouns: ‘tú mismo’ (‘yourself’ ), ‘él mismo’ (‘himself’), ‘ella misma’ (‘herself’), ‘oneself’ (‘uno mismo’) and so on.

Of course, this IS also the case in Mexican Spanish, but you’ll definitely sound more native if you replace ‘mismo’ with ‘mero’!

Yo mero me aseguré de que todas las ventanas estuvieran cerradas.

I made sure all the windows were closed myself.


Gibrán – ¿Ella es la chica de la que me has platicado?

Sandra – ¡Ella mera!



Gibrán – Is she the girl you told me about?

Sandra – That’s her in the flesh!

2 Yo merolas – Myself

Any Mexican expression that ever was and ever will be is always gonna be warped into further variations, normally by replacing a word with a similar word that sounds funny, rhymes, or simply rolls off the tongue. That’s Mexican Spanish for you in a nutshell!

Such is the case with ‘yo merolas’, which is just a fun way to say ‘yo mero’.

Amelia – ¿Quién trajo este pastel?

Ingrid – ¡Yo merolas!



Amelia – Who brought the cake?

Ingrid – I did!

3 Yo merengues – Myself

‘Merengue’ means ‘meringue’ in English (as in the sweet mixture of sugar with white eggs that’s used in desserts).

Does it really have anything to do with ‘yo mero’? Nope. It’s just another fun way to say ‘yo mero’!

Manuel – ¿Quién te dijo que podías traer invitados?

Alma – ¡Tú merengues!

Manuel – ¿Yo? Ah caray, no lo recuerdo…



Manuel – Who told you that you could bring guests?

Soul – You did!

Manuel – Me? Darn, I don’t remember …


As a synonym of ‘right’ (i.e., ‘exactly‘)


4 Ahí mero – Right there

Ahí mero’ is an extremely common way to indicate a particular location.

Leticia – No encuentro mi celular, ¿lo has visto?

Rafa – ¡Está ahí mero en tu bolsillo!



Leticia – I can’t find my cell phone, have you seen it?

Rafa – It’s right there in your pocket!



5 Así mero – Exactly like that

‘Así’ means ‘like that’ in English, so the expression ‘así mero’ could be translated as ‘exactly like that’ or ‘precisely that’.

En clase de cocina

Víctor – ¿Está bien si cortó la cebolla de esta forma?

Maestra – ¡Así mero!



In cooking class

Víctor – Is it okay if I cut the onion like this?

Teacher – Exactly like that!

6 La mera neta – The honest truth

As it turns out, BOTH ‘neta’ and ‘mera’ mean ‘pure’ in English, so ‘la mera neta*should* translate to something like the ‘purest purity’ … except it doesn’t!

‘Neta’ is actually an extremely common way of saying ‘truth’ in Mexican slang, so ‘la mera neta’ refers to the ‘honest / absolute truth’.

La mera neta no me gusta nada esta situación.

To be perfectly honest, I don’t like this situation at all.



Ese wey siempre me dice la mera neta; por eso le pido consejo.

That guy always tells me the truth; that’s why I go to him for advice.




7 A lo mero macho – the absolute truth / the very bravest

‘Macho’ is a complex Spanish term that can have either positive or negative connotations, but in the phrase ‘a lo mero macho’ it refers to ‘bravery’ or ‘straightforwardness’.

And what does ‘mero’ have to do with ‘macho’?

Well, not much to be honest; in this phrase it’s basically used as an “intensifier”!

Renunció de su trabajo, así nomás, a lo mero macho.

He quit his job just like that, unflinchingly.



Te lo digo a lo mero macho: ese vecino me da mala espina.

I’m telling you for real: that neighbor gives me a bad feeling.


To describe someone/something important


8 Mero mole – My jam

‘Mero mole’ is a fun Mexican expression used to describe something that’s your “jam”.

Think that activity / subject that you’re super passionate about, your area of expertise, or THAT thing that makes your heart skip a beat!

If you think ‘mole’ sounds familiar, well, it probably is …. ‘mole’ is a traditional Mexican dish, and many people’s personal favorite (maybe that’s why ‘mero mole’ means something that you REALLY like!)

Yep, just like ‘el mero mero’.
