Marinamos el solomillo hoy.

Marinamos tells you the subject is we.

It is the first-person plural form of marinar in the indicative. So the sentence is built around we marinate / we are marinating / we marinated, depending on context.

Because the verb ending already shows we, Spanish usually does not need the subject pronoun nosotros.

Spanish often drops subject pronouns because the verb ending already makes the subject clear.

• Marinamos = we marinate
• Marino = I marinate
• Marinan = they / you all marinate

So Marinamos el solomillo hoy is perfectly natural without nosotros.

You could say Nosotros marinamos el solomillo hoy, but that adds emphasis, as if you were contrasting we with someone else.

It can be either, depending on context.

For regular -ar verbs, the nosotros form is the same in:

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

So this form is ambiguous by itself.

Context usually clears it up:

• Hoy marinamos el solomillo can mean We marinate / are marinating the tenderloin today
• In some contexts, especially in Spain, it could also mean We marinated the tenderloin today

If the meaning shown to the learner is present, then the context is pushing you toward that reading.

Spanish often uses the simple present where English might prefer either simple present or present continuous.

So Marinamos el solomillo hoy can sound natural for:

• something happening now
• something planned for today
• a general statement about today’s action

Estamos marinando el solomillo is more specifically focused on the action being in progress right now.

Very roughly:

• Marinamos el solomillo hoy = We’re marinating the tenderloin today
• Estamos marinando el solomillo ahora = We’re marinating the tenderloin right now

Spanish uses articles more often than English.

Here, el solomillo refers to the tenderloin, meaning a specific piece of meat that the speakers have in mind. In English, we sometimes leave out the in cooking contexts, but Spanish often keeps it.

So even if English might say:

• We’re marinating tenderloin today

Spanish naturally says:

• Marinamos el solomillo hoy

In Spain, solomillo usually means tenderloin or fillet, especially a high-quality cut of meat.

Depending on context, it can refer to:

• beef tenderloin
• pork tenderloin

If no animal is specified, the exact type may depend on the recipe, the meal, or the wider conversation.

So solomillo is not just any steak or any piece of meat; it refers to a particular cut.

Yes, hoy can move.

Spanish word order is more flexible than English, especially with time expressions. All of these are possible:

• Marinamos el solomillo hoy
• Hoy marinamos el solomillo
• El solomillo lo marinamos hoy — more marked, with extra emphasis

Putting hoy at the end is completely natural. It often sounds neutral, with the time information added after the main action.

Putting hoy first can give a little more emphasis to today.

Yes. El solomillo is the direct object of marinamos.

The structure is:

• Marinamos = verb
• el solomillo = what is being marinated
• hoy = time expression

So the sentence pattern is basically:

We + marinate + the tenderloin + today

A simple approximate pronunciation for an English speaker is:

mah-ree-NAH-mos el soh-loh-MEE-yoh oy

A few helpful points for Spain:

• r in marinamos is a light tap
• ll in solomillo is commonly pronounced like y
• hoy has a clear oy sound, similar to English boy without the initial b

Natural stress:

• mariNAmos
• soloMIllo

So the rhythm is:

mariNAmos el solomillo HOY
