Antes de abrir el cajón de abajo, me agacho porque la cómoda es muy baja.

Because after antes de, Spanish normally uses an infinitive when the subject stays the same.

• Antes de abrir el cajón... = Before opening the drawer... / Before I open the drawer...
• You do not use a conjugated verb like abro after antes de in this structure.

A useful rule:

• antes de + infinitive → when the same person does both actions
• antes de que + subjunctive → when the subject changes

Examples:

• Antes de salir, apago la luz. = Before leaving, I turn off the light.
• Antes de que salgas, apago la luz. = Before you leave, I turn off the light.

Agacharse is a pronominal verb, so it is normally used with a reflexive-style pronoun:

• me agacho = I bend down / I crouch
• te agachas = you bend down
• se agacha = he/she bends down

Here, me does not literally mean myself in a strong way. It is simply part of how this verb is commonly used.

So:

• agacho by itself would sound incomplete or unnatural in this meaning
• me agacho is the normal form

Here agacharse means to bend down, to stoop, or sometimes to crouch down.

In this sentence, the idea is that the speaker lowers their body in order to reach the lower drawer because the piece of furniture is low.

It does not usually mean a full formal squat unless the context suggests that. Bend down is probably the most natural everyday translation here.

De abajo works like the one at the bottom / the lower one.

So:

• el cajón de abajo = the bottom drawer / the lower drawer

Spanish often uses this pattern:

• el de arriba = the one above / the top one
• el de abajo = the one below / the bottom one

Just saying el cajón abajo would usually sound incomplete or unnatural here. De abajo is the normal expression.

Yes, you could, but it sounds more formal or descriptive.

Compare:

• el cajón de abajo = the bottom drawer, very natural in everyday speech
• el cajón inferior = the lower drawer, a bit more formal or technical

In normal conversation, de abajo is usually the more common choice.

Yes. Cómoda can mean two different things:

1. cómoda as an adjective = comfortable

   • una silla cómoda = a comfortable chair

2. la cómoda as a noun = chest of drawers / dresser

   • La cómoda es muy baja. = The chest of drawers is very low.

The article la helps show that it is being used as a noun here.

So in this sentence, la cómoda is the furniture, not the adjective comfortable.

These are just the grammatical genders of the nouns:

• el cajón = masculine
• la cómoda = feminine

Sometimes gender follows patterns, but often you simply have to learn the noun with its article.

A few helpful clues here:

• nouns ending in -ón are often masculine: el cajón
• many nouns ending in -a are feminine: la cómoda

But the best habit is to memorize them together with the article:

• el cajón
• la cómoda

Because baja describes la cómoda, which is a feminine singular noun.

Adjectives in Spanish usually agree with the noun they describe:

• la cómoda → feminine singular
• therefore baja → feminine singular

Compare:

• El mueble es muy bajo.
• La cómoda es muy baja.

So baja is there because it matches la cómoda.

Here it means low.

For furniture, Spanish often uses bajo/baja to talk about height:

• una mesa baja = a low table
• una cómoda baja = a low chest of drawers

With people, bajo/baja can often mean short:

• Es baja. = She is short.

So the exact English translation depends on what is being described.

Because Spanish usually leaves out subject pronouns when the verb ending already makes the subject clear.

• me agacho already tells you it means I bend down
• adding yo is possible, but not necessary

Spanish is a pro-drop language, so this is very normal.

You might add yo only for emphasis or contrast:

• Yo me agacho, pero tú no. = I bend down, but you don’t.

Because porque is the conjunction meaning because.

In Spanish, these are different:

• porque = because
• por qué = why
• por que = less common combination in other structures
• porqué = a noun meaning reason

Here the sentence gives a reason:

• me agacho porque la cómoda es muy baja
• I bend down because the chest of drawers is very low

So porque is the correct form.

The comma separates the introductory phrase from the main clause:

• Antes de abrir el cajón de abajo, = introductory time clause
• me agacho... = main clause

In Spanish, this comma is very natural and helps readability.

You may sometimes see short introductory phrases without a comma, but in a sentence like this, using the comma is standard and clear.

Cajón has a written accent because the stress falls on the last syllable: ca-JÓN.

Spanish spelling rules say that words stressed on the last syllable usually need a written accent if they end in:

• n
• s
• a vowel

Since cajón ends in n and the stress is on the last syllable, it needs the accent mark.

Yes, literally it means the drawer below, but in many everyday contexts that naturally becomes the bottom drawer or the lower drawer.

So the exact English wording depends on the situation:

• if there are several drawers, it may mean the lower drawer
• if it is the lowest one, the bottom drawer is the most natural translation

Spanish often leaves that kind of detail to context.

Yes. In Spain, cómoda commonly refers to a piece of bedroom furniture with drawers, often translated as chest of drawers or dresser depending on the variety of English.

A rough guide:

• cómoda = chest of drawers / dresser
• cajón = drawer

So la cómoda is the whole piece of furniture, and el cajón is one drawer in it.
