Cribamos el compost.

Cribamos is the first-person plural form of cribar in the present indicative.

So, as written, it means we sift or we screen.

It comes from the regular -ar verb pattern:

• cribo = I sift
• cribas = you sift
• criba = he/she/it sifts
• cribamos = we sift

In standard Spanish, cribamos means we sift.

If you want let’s sift the compost, the normal form is cribemos el compost.

That is an important distinction:

• Cribamos el compost = We sift the compost
• Cribemos el compost = Let’s sift the compost

So if the intended meaning shown to the learner is let’s sift the compost, the sentence should normally be Cribemos el compost.

Spanish often leaves out subject pronouns because the verb ending already tells you who is doing the action.

Here, cribamos already clearly means we, so nosotros is unnecessary.

You could say Nosotros cribamos el compost, but that usually adds emphasis, contrast, or clarity, for example:

• Nosotros cribamos el compost y ellos lo riegan.

On its own, Cribamos el compost is perfectly normal.

In Spain, compost is normally treated as a masculine noun, so you say el compost.

This is one of those borrowed words whose gender is fixed by usage rather than by its ending.

So in Spain:

• el compost

In some Latin American varieties, you may also hear:

• la composta

But for Spanish from Spain, el compost is the form learners should expect.

Yes, compost is a common and natural word in Spain, especially in gardening, agriculture, and recycling contexts.

Some related words are:

• compost = compost, the material
• compostaje = composting, the process
• abono = fertiliser / compost / manure, depending on context

If you are talking specifically about the compost material you are handling, el compost sounds very natural in Spain.

Yes, you could sometimes use tamizar, but cribar is very suitable here.

Cribar means to pass something through a screen, sieve, or mesh. That fits very well with compost, because people often remove larger bits and leave a finer material behind.

Tamizar also means to sift or to sieve, but it can sound a bit more technical or more associated with finer powders and cooking contexts.

So for garden compost, cribar el compost is a very natural choice.

Spanish usually uses the definite article when talking about a specific thing already known in the situation.

So el compost here means something like the compost we are dealing with.

Without the article, cribamos compost sounds much less natural in this kind of sentence. It feels too general or incomplete.

So:

• Cribamos el compost = natural, specific
• Cribamos compost = possible only in very special contexts, but not the normal choice

A good approximate pronunciation is:

kree-BA-mos el kom-POST

A few useful details:

• cri- sounds like kree
• the stress in cribamos is on BA
• c before r sounds like a hard k
• the b in Spanish is softer than English b, especially between vowels
• compost is usually stressed on the last syllable: com-POST

A more phonetic version would be:

kree-BA-mos el kom-POST
