In Spanish, physical sensations like being cold, hot, hungry, or thirsty are often expressed with tener (to have), not ser or estar.
So:
Other common examples:
This is just a normal Spanish pattern you need to learn as a chunk: tener + noun for many physical states.
The accent mark shows the correct stress and also helps show that í and o are pronounced in separate syllables:
Without the accent, Spanish spelling rules would suggest a different stress pattern. So the written accent is necessary.
Because the verb is cerrar (to close), and in the present tense it is a stem-changing verb:
The stem changes from e to ie in most forms, including cierra.
So:
In Spanish, the subject pronoun is often omitted because the verb ending usually makes the subject clear.
Here, cierra is the él/ella/usted form, and the subject already mentioned is mi amiga, so it means:
Spanish avoids repeating the subject when it is already clear.
Because Spanish often drops subject pronouns like yo, tú, él, ella when they are not needed.
English usually says:
Spanish normally says:
The she is understood from mi amiga and the verb form cierra.
Spanish often uses the definite article (el, la, los, las) more often than English does.
So la ventana means the window. In this sentence, it sounds natural because it refers to a specific window in the situation.
Even when English might sometimes leave something more general, Spanish often keeps the article.
It can be either, depending on context. The Spanish present tense often covers both the simple present and the present progressive in English.
So cierra la ventana can mean:
In an isolated sentence like this, English often uses closes, but the exact translation depends on context.
A simple pronunciation guide is:
mee ah-MEE-gah TYEH-neh FREE-oh ee SYEH-rrah lah ben-TAH-nah
A few notes:
Not if you mean she feels cold.
But está fría usually describes something that is cold to the touch or in temperature, and with a person it can sound like you are describing their body, manner, or emotional coldness depending on context.
So for the physical sensation a person feels, tener frío is the normal choice.
