L'entrenador mira la postura.

Because el becomes l' before a singular noun that starts with a vowel or silent h.

• el entrenador → l'entrenador
• This is called elision

So L'entrenador still means the coach / the trainer, just with the article shortened for pronunciation.

Entrenador usually means coach or trainer, especially in sports, exercise, or physical training contexts.

It is a masculine singular noun here.

• l'entrenador = the male coach / the coach
• Feminine: l'entrenadora = the female coach

Sometimes English can translate it in more than one way depending on context.

Mira is the 3rd person singular present indicative of the verb mirar (to look, to watch, to observe).

So it matches:

• ell mira = he looks / he watches
• ella mira = she looks / she watches
• l'entrenador mira = the coach looks / watches

In this sentence, it agrees with l'entrenador, which is singular.

Because Catalan often uses mirar directly with an object, where English usually says look at.

So:

• mira la postura = literally looks the posture
• natural English: looks at the posture

This is a very common difference between Catalan and English. Catalan does not need a preposition here.

Because postura is a feminine singular noun, so it takes the feminine singular definite article la.

• la postura = the posture

The ending -a often signals a feminine noun in Catalan, and that is true here.

Postura means posture, position, or sometimes stance, depending on context.

In this sentence, the most natural meaning is physical posture—for example, how someone is standing, sitting, or holding their body.

Because Catalan usually omits subject pronouns when they are not needed.

The verb form and the noun already show who is doing the action:

• L'entrenador mira la postura.

You could say Ell mira la postura, but here it would be unnecessary because l'entrenador is already the subject.

This is normal in Catalan.

No, this is the normal Subject–Verb–Object order:

• L'entrenador = subject
• mira = verb
• la postura = object

So the sentence structure is very straightforward and similar to English.

Yes. The Catalan present tense can often cover both meanings, depending on context.

So mira can mean:

• looks
• is looking
• sometimes watches or is watching

Without more context, the sentence could be understood in more than one natural way in English.

The main thing to notice is that l' attaches smoothly to the next word:

• L'entrenador

You do not pronounce a full separate el. The article is reduced to just the l sound before the noun.

A rough guide for an English speaker is:

• len-truh-nuh-DOR or lun-truh-nuh-DOR

The exact pronunciation varies by dialect, but the important point is that the article and noun flow together as one unit.

Yes, depending on context.

The verb mirar can mean:

• look at
• watch
• observe

So if the coach is paying attention to someone’s body position, English might translate it as:

• The coach looks at the posture
• The coach watches the posture
• The coach observes the posture

The best translation depends on the situation.

Yes. It is a complete, correct Catalan sentence.

It has:

• a subject: L'entrenador
• a verb: mira
• an object: la postura

So even though it is short, it is fully grammatical and natural.
