El colador está en el cajón de la cocina, al lado de las cucharas.

Because this sentence talks about location, and in Spanish location is normally expressed with estar, not ser.

• El colador está en el cajón = The colander/strainer is in the drawer
• Ser is usually for identity, origin, characteristics, etc.
• Estar is usually for location, condition, and temporary states

So El colador es en el cajón would be incorrect.

Colador usually means strainer or colander, depending on context.

In a kitchen sentence like this, it often refers to a tool used to drain pasta or rinse food. English uses different words more strictly, but Spanish colador can cover both ideas in everyday use.

Spanish uses definite articles (el, la, los, las) more often than English.

So El colador literally means the colander/strainer, and it sounds natural in Spanish because you are referring to a specific object. In English, you might sometimes drop the article in certain contexts, but Spanish usually keeps it.

Because grammatical gender in Spanish is not decided only by the final letters. While many nouns ending in -o are masculine and many ending in -a are feminine, there are lots of other endings too.

Cajón is a masculine noun, so it takes el:

• el cajón
• un cajón

You generally have to learn the gender along with the noun.

En means in, inside, or sometimes on/at, depending on context.

Here, en el cajón means in the drawer, because the object is located inside it.

You would not use a here, because a usually means to or marks a direct object in some cases. Since this is about location, en is the correct preposition.

De la cocina means of the kitchen or, more naturally in English, in the kitchen / kitchen.

So:

• el cajón de la cocina = the kitchen drawer / the drawer in the kitchen

Spanish often uses de where English might use a noun directly as an adjective:

• el libro de historia = the history book
• la mesa del comedor = the dining-room table

Here, de la cocina specifies which drawer you mean.

Because cocina is a feminine noun:

• la cocina = the kitchen

The contraction del only happens with de + el:

• de + el = del

But with feminine la, there is no contraction:

• de la cocina, not del cocina

Al lado de means next to or beside.

It is a very common expression for location:

• al lado de la mesa = next to the table
• al lado del horno = next to the oven

Literally, it comes from:

• a + el = al
• lado = side
• de = of

So it is literally something like at the side of, but the natural English meaning is next to.

Because the full expression is al lado de. The de is required.

So the structure is:

• al lado de + noun

Examples:

• al lado de la puerta
• al lado del fregadero
• al lado de las cucharas

Without de, the phrase is incomplete.

Because cucharas is:

1. plural
2. feminine

Singular:

• la cuchara = the spoon

Plural:

• las cucharas = the spoons

The article must match the noun in gender and number:

• la cuchara
• las cucharas

Yes. Junto a is another common way to say next to.

So these are both natural:

• al lado de las cucharas
• junto a las cucharas

They mean almost the same thing. Al lado de may feel slightly more literal as at the side of, but both are very common and correct.

The accent mark shows which syllable is stressed:

• es-TÁ

It also helps distinguish forms in writing. Here está is the he/she/it is or you are form of estar.

Without the accent, esta is usually a demonstrative adjective meaning this:

• esta cuchara = this spoon

So the accent is important.

Yes. Cajón is stressed on the last syllable:

• ca-JÓN

The written accent tells you that. Also:

• j in Spanish is pronounced like a strong throaty h sound
• ó shows the stressed syllable

So the word sounds roughly like ka-HON.

The comma separates two pieces of location information:

• está en el cajón de la cocina
• al lado de las cucharas

The second part adds extra detail about where exactly in the drawer the object is. In English, you might also use a comma in a similar sentence, although punctuation can vary a bit. The comma here helps readability, but the meaning would still be clear without it in many contexts.

In many contexts, cocina means kitchen, as it does here.

In some varieties or situations, it can also refer to a stove/cooker, but in this sentence el cajón de la cocina clearly means the kitchen drawer or the drawer in the kitchen, not a drawer belonging to a stove.

Context usually makes the meaning clear.

The singular is cuchara, which means spoon. The ending -s marks the plural:

• cuchara = spoon
• cucharas = spoons

This is one of the most common plural patterns in Spanish:

• vowel-ending noun + s

For example:

• casa / casas
• mesa / mesas
• cuchara / cucharas
