Marinamos la carne antes de asarla y avivamos el fuego.

Because both are nosotros forms of -ar verbs:

• marinar → marinamos
• avivar → avivamos

A useful thing to know is that for -ar verbs, -amos can be either:

• present: we marinate / we are marinating / we marinate
• preterite: we marinated

So this form is ambiguous by itself. Only the wider context tells you whether it is present or past.

Yes. Marinamos comes from marinar, which means to marinate.

It is very close to the English verb in both meaning and use:

• Marinamos la carne = We marinate the meat / We marinated the meat

Because the meaning has already been given, the main thing to notice is the grammar: it is the we form of marinar.

They are both la, but they do different jobs.

• la carne: here la is the definite article = the
• asarla: here la is a direct object pronoun = it, referring back to la carne

So:

• la carne = the meat
• asarla = to roast it, where it = the meat

Because asar is in the infinitive, and Spanish allows object pronouns to attach directly to an infinitive.

So:

• asar + la → asarla

This is very common in Spanish:

• comerlo = to eat it
• hacerla = to do/make it
• verlos = to see them

In this sentence, la refers to la carne.

Because after antes, Spanish normally uses de before an infinitive.

The pattern is:

• antes de + infinitive

So:

• antes de asarla = before roasting it
• antes de comer = before eating
• antes de salir = before leaving

If a full clause follows instead of an infinitive, you usually get:

• antes de que + subjunctive

Example:

• antes de que lleguemos = before we arrive

Avivar means to make something stronger, livelier, or more intense.

With fuego, it usually means something like:

• to stoke the fire
• to revive the fire
• to fan the flames

So avivamos el fuego suggests making the fire burn more strongly.

In a cooking context, that is a natural meaning.

Avivar is completely correct and natural, especially with fuego or flames. It can sound a little more descriptive or literary than some basic verbs, but it is absolutely standard.

Other possibilities, depending on context, include:

• atizar el fuego = to stoke the fire
• echar más leña al fuego = to add more wood to the fire

But avivar el fuego is a very good, idiomatic choice.

Spanish uses the definite article more often than English does.

So Spanish often says:

• la carne
• el fuego

where English may sometimes say just:

• meat
• fire

or use the, depending on the context.

In this sentence, la carne and el fuego sound perfectly normal and natural in Spanish. English and Spanish do not always match exactly in article usage.

Yes, absolutely.

Both are correct:

• antes de asar la carne
• antes de asarla

The second version avoids repeating la carne, because la already stands for it.

So the difference is mostly about style and repetition:

• antes de asar la carne = more explicit
• antes de asarla = more compact and natural once la carne has already been mentioned

It is made of:

• asar = to roast / to grill
• la = it (referring to la carne)

So:

• asar + la → asarla

This is a very useful pattern in Spanish. You can do the same with other pronouns:

• asarlo = to roast it (for a masculine object)
• asarlos = to roast them
• asarlas = to roast them (feminine plural)

It can mean to roast, to grill, or more generally to cook over direct heat, depending on the context.

So asarla could be understood as:

• to roast it
• to grill it

In a sentence with el fuego, the idea is clearly cooking meat over heat or flame, so either translation may work depending on how the meaning was presented to the learner.

A broad Spain pronunciation would be roughly:

ma-ri-NA-mos la KAR-ne AN-tes de a-SAR-la i a-bi-BA-mos el FWE-go

A few useful points:

• h is not an issue here, but in general Spanish h is silent
• v and b are pronounced very similarly in Spanish, so avivamos sounds close to having b
• y meaning and is pronounced like i
• the stress falls naturally on:
  • mariNAmos
  • aSARla
  • aviVAmos

You do not need to exaggerate anything; a clear, steady rhythm is more important.

It has two coordinated actions, both with an understood we:

• Marinamos la carne = We marinate / marinated the meat
• antes de asarla = before roasting it
• y avivamos el fuego = and we stoke / stoked the fire

So the structure is:

• [main verb] + [object] + [time expression with infinitive] + y + [second main verb] + [object]

This is a very common Spanish sentence pattern.
