How Mexicans use “mero”, “ya mero”, “aquí mero”, “el mero mero”, “yo mero” and more, plus the formal word “mero” and “meramente”.

What does “mero” mean?

In standard Spanish, mero can mean things like “mere / pure / simple” and it is also the name of a fish (a grouper).

In Mexican Spanish, though, mero has several very common, fun uses in everyday speech. Depending on the context, it can mean:

• almost / about to happen (ya mero, ya merito)
• exactly here / right there / that one (aquí mero, ahí mero, ése mero)
• the main one / the real boss (el mero mero)
• me myself (yo mero)
• just / only / pure (mero trámite, la mera verdad)

“Ya mero” / “ya merito” – almost, very soon

Mexicans say ya mero when something is about to happen, when you are almost there or almost finished, or when you want to buy a little time.

You will also hear ya merito, which is very similar but often sounds even closer in time, like “almost, almost” or “any second now”.

Sometimes people use ya mero / ya merito a bit jokingly, when someone is always “almost” doing something but never really does it.

“Aquí mero / ahí mero / ése mero” – exactly here, that one

When you hear aquí mero, it usually means “right here, exactly here”, with a bit of Mexican flavor.

Aquí mero es.
“It’s right here.”

Nos vemos ahí mero, en la esquina.
“Let’s meet right there, on the corner.”

Pon la carro aquí mero.
“Put the car right here.”

You can also say ése mero / esa mera to mean “that exact one, that same one”.

—¿Este libro?
—Sí, ése mero.
“—This book? —Yes, that one exactly.”

Ése mero fue el que te llamó por teléfono.
“That one right there is the one who called you on the phone.”

“El mero mero” or “La mera mera”– the main boss

The expression el mero mero (for women la mera mera) is a playful way to say “the main one, the boss, the top person, the one in charge”.

¿Quién es el mero mero de esta oficina?
“Who is the main boss in this office?”

Ella es la mera mera del equipo.
“He is the top guy on the team.”

Sometimes people make it longer and more joking, for example **“el mero mero petatero”** in some regions.

“Yo mero” or “Yo mera” – me, myself

Yo mero (yo mera) means “me, myself, the very one”, like saying “me personally” or “yours truly”. It shows that it was really you and not someone else.

¿Quién lo hizo? —Yo mero.
“Who did it? —Me. (I did it.)”

Yo mero te ayudo si necesitas algo.
“I’ll personally help you if you need something.”

“Mero” and “meramente” in more formal Spanish

Outside of Mexican slang, mero / mera and meramente also appear in more formal, standard Spanish.

• As an adjective, mero / mera can mean “mere / simple / pure / nothing more than”:
  • Es un mero trámite. – “It’s just a formality.”
  • Por mero interés. – “Out of mere interest.”
• The adverb meramente means “merely / purely / simply”:
  • Es un asunto meramente administrativo. – “It’s a purely administrative matter.”
  • La reunión fue meramente informativa. – “The meeting was merely informative.”

So the Mexican uses like ya mero, aquí mero, el mero mero, yo mero are like “cousins” of this more formal idea: exact, pure, just this and nothing else. The slang forms keep the idea of emphasis, but in a very friendly, everyday way.
