Tengo frío en la galería.

In Spanish, feeling cold is usually expressed with tener + a noun:

• tener frío = to feel cold

So tengo frío is the normal way to say I’m cold.

By contrast:

• estoy frío/fría usually describes your physical state more literally, as in my body is cold or I’m cold to the touch
• soy frío/fría means I am cold as a person, like emotionally distant

So for the normal sensation, tengo frío is the natural choice.

Here, frío acts like a noun, meaning something like cold or coldness, in the expression tener frío.

That is why it does not agree with the speaker:

• Tengo frío
• Ella tiene frío
• Nosotros tenemos frío

It stays frío for everyone.

But when frío is an adjective, it does agree:

• La sopa está fría
• El café está frío

So in tengo frío, think of it as part of a fixed expression rather than a normal adjective.

Spanish often leaves out subject pronouns because the verb ending already shows who the subject is.

• tengo already means I have

So Tengo frío en la galería naturally means I am cold in the gallery/porch/balcony without needing yo.

You can add yo if you want emphasis or contrast:

• Yo tengo frío en la galería, pero él no.

With many common expressions of physical sensations or needs, Spanish uses tener + noun with no article:

• tener hambre
• tener sed
• tener sueño
• tener calor
• tener frío
• tener miedo

So tengo frío is correct, not tengo un frío in normal usage.

Because en shows location, while a usually shows movement toward a place.

• en la galería = in/on/at the gallery, porch, balcony, etc.
• a la galería = to the gallery

So:

• Tengo frío en la galería = I’m cold in the gallery/porch/balcony
• Voy a la galería = I’m going to the gallery/porch/balcony

It depends a lot on the country and context. In Latin America, galería can mean things like:

• a gallery
• a balcony
• a porch or veranda
• a covered corridor
• sometimes even a shopping arcade

So the best translation depends on where the Spanish is being spoken and what kind of place is being described.

Because galería is a feminine singular noun, so it takes la.

• la galería
• las galerías

Also, there is no contraction with en. Spanish only has these two standard contractions:

• a + el = al
• de + el = del

So en la stays en la.

Use a different structure, because the meaning changes:

• Tengo frío en la galería = I feel cold in the galería
• Hace frío en la galería = It’s cold in the galería

So tener frío talks about a person’s sensation, while hacer frío talks about the temperature or conditions.

You might also hear:

• La galería está fría = The galería is cold

That focuses on the place itself, not on how a person feels.

Yes. Spanish word order is flexible.

The original sentence:

• Tengo frío en la galería

is the most neutral version.

You can also say:

• En la galería tengo frío

This puts more emphasis on where you feel cold.

Both are correct; the difference is mostly emphasis.

A simple Latin American-style approximation is:

• frío = FREE-oh
• galería = gah-leh-REE-ah

A couple of helpful points:

• frío has two syllables: frí-o
• galería is stressed on rí
• the written accent marks show where the stress goes

So the full sentence sounds roughly like:

• TEN-go FREE-oh en la gah-leh-REE-ah
