En esa tienda venden mayonesa, vinagre y pimienta en el mismo pasillo.

Starting with En esa tienda puts the location first: In that shop/store...

Spanish is flexible with word order, so this sentence could also be:

Venden mayonesa, vinagre y pimienta en el mismo pasillo en esa tienda.

But that sounds less natural here. Putting En esa tienda first sets the scene right away and is very common in Spanish.

Esa means that.

In Spanish, demonstratives often depend on distance or perspective:

• esta tienda = this shop
• esa tienda = that shop
• aquella tienda = that shop over there / that shop further away

In modern Spanish, especially in everyday speech, ese/esa is very commonly used for that.

Usually, yes. Tienda means shop or store.

Depending on context, Spanish can also use more specific words:

• supermercado = supermarket
• panadería = bakery
• farmacia = pharmacy

Here, tienda is a general word, and it works fine.

Venden is the they sell form of vender.

But in sentences like this, Spanish often uses the 3rd person plural in a general, impersonal way, where English might say:

• They sell...
• You can buy...
• They have...

So En esa tienda venden... does not necessarily mean a specific group of people. It often just means they sell ... there or that shop sells ...

Yes, a similar idea could be expressed with se venden, but the structure would be slightly different.

For example:

• En esa tienda venden mayonesa, vinagre y pimienta...
• En esa tienda se venden mayonesa, vinagre y pimienta...

Both can sound natural, but venden is often a bit more straightforward and conversational here.

The se construction is common for more impersonal or formal statements, especially in written notices and general descriptions.

Because Spanish often leaves out articles when listing things in a general way.

So:

• venden mayonesa, vinagre y pimienta = they sell mayonnaise, vinegar and pepper

This is normal when talking about products or categories in general.

If you added articles, it could sound more specific, depending on context:

• la mayonesa = the mayonnaise
• el vinagre = the vinegar
• la pimienta = the pepper

But in a simple product list, no articles is the most natural choice.

Because y normally means and.

Spanish changes y to e only before words that begin with an i sound:

• padre e hijo
• vino e hielo

But pimienta starts with a p sound, so it stays y:

• vinagre y pimienta

Because in Spanish, as in standard English, you normally do not put a comma before y in a simple list.

So this is normal:

• mayonesa, vinagre y pimienta

That is the usual Spanish style. The Oxford comma is generally not used in ordinary Spanish lists.

Here, pasillo means aisle.

In a shop or supermarket, pasillo is the row or section between shelves.

So en el mismo pasillo means that all those items are found in the same aisle.

Because Spanish usually needs the article here: el mismo pasillo = the same aisle.

The word mismo often appears with a definite article in expressions like:

• el mismo día = the same day
• la misma calle = the same street
• el mismo pasillo = the same aisle

So en el mismo pasillo is the normal structure.

Mismo means same here.

So:

• el pasillo = the aisle
• el mismo pasillo = the same aisle

It tells you that mayonnaise, vinegar, and pepper are all located in one shared aisle, not in different parts of the store.

Because the sentence contains two different prepositional phrases:

• En esa tienda = in that shop
• en el mismo pasillo = in the same aisle

Both use en because both refer to location.

So the sentence first tells you the larger place, then the more specific place inside it.

Usually pimienta means pepper as a spice, especially black pepper or ground pepper.

It does not usually mean bell pepper. For that, Spanish normally uses:

• pimiento = pepper / bell pepper

So in this sentence, pimienta is the seasoning, not the vegetable.

Yes. Mayonesa is the standard word.

You may also sometimes see the spelling mahonesa, which is also accepted and has historical use in Spain, but mayonesa is the more common spelling for most learners to know.

Vinagre is masculine:

• el vinagre

That can be surprising because it ends in -e, not -o. Nouns ending in -e can be either masculine or feminine, so you often just have to learn them with the article.

It means they are found in the same aisle, not necessarily sold as a set.

So the idea is about location in the shop, not packaging or promotion.

A learner might be tempted to read it as all together, but en el mismo pasillo specifically points to where they are in the store.

Sometimes, but the meaning changes slightly.

• pasillo = aisle
• sección = section / department

In a supermarket, pasillo is more physical and precise: the actual aisle between shelves.

Sección is broader, like a department or category area.

So pasillo is the better choice if you mean aisle.

Yes, it is natural and clear.

A Spanish speaker might also say things like:

• En esa tienda, la mayonesa, el vinagre y la pimienta están en el mismo pasillo.
• En esa tienda encuentras la mayonesa, el vinagre y la pimienta en el mismo pasillo.

But the original sentence sounds perfectly normal and understandable.
