El jersey azul va bien con la bufanda roja.

Yes, ir usually means to go, but in the expression ir bien con, it means to go well with, to match, or to suit.

So:

• va = goes
• bien = well
• con = with

Literally, it is something like The blue sweater goes well with the red scarf, which is very close to natural English anyway.

This is a very common way to talk about clothes, colours, and style in Spanish.

In Spanish, descriptive adjectives usually come after the noun, especially with things like colour, size, and shape.

So:

• el jersey azul = the blue sweater
• la bufanda roja = the red scarf

That is the normal word order in Spanish.
Putting colour adjectives before the noun would usually sound unnatural here.

Because Spanish nouns have grammatical gender.

• jersey is masculine, so it takes el
• bufanda is feminine, so it takes la

This gender is part of the noun, and it affects the words around it, such as articles and adjectives.

So:

• el jersey azul
• la bufanda roja

Even when the object itself has no biological sex, the noun still has grammatical gender.

Because Spanish adjectives must agree with the noun they describe in gender and number, but not all adjectives change in the same way.

• rojo changes:
  • masculine singular: rojo
  • feminine singular: roja
  • masculine plural: rojos
  • feminine plural: rojas

Since bufanda is feminine singular, you get roja.

But azul is different:

• masculine singular: azul
• feminine singular: azul
• plural: azules

So azul does not change for gender in the singular, but it does change in the plural.

Because the subject is el jersey azul, which is singular.

The verb ir must agree with its subject:

• el jersey azul va
• los jerséis azules van

So the sentence uses va because it is talking about one sweater.

Yes. In Spain, jersey is a very common word for sweater or jumper.

It originally came from English, but it is fully established in Spanish. This is especially useful to know because vocabulary for clothes varies a lot across the Spanish-speaking world.

For example:

• in Spain: jersey
• in some other countries, you might hear suéter or other regional words

So for Spanish from Spain, jersey is completely normal.

Yes, absolutely.

• va bien con = goes well with
• combina bien con = matches well with
• queda bien con can also be used in some contexts

All of these can work, but they are not always identical in tone:

• va bien con sounds very natural and everyday
• combina bien con sounds a bit more directly about matching
• queda bien con can suggest that something looks good with something else

So El jersey azul va bien con la bufanda roja is a very natural sentence.

Because the expression is ir bien con: to go well with.

The preposition con means with, and it links the two items being compared or matched:

• el jersey azul
  • con
    • la bufanda roja

So if you want to say one item goes well with another, con is the normal preposition.

Usually no, not in this kind of sentence.

Spanish uses definite articles much more often than English does. Here, el jersey azul and la bufanda roja refer to specific items, so the articles sound natural and expected.

Compare:

• El jersey azul va bien con la bufanda roja = talking about specific items
• Jersey azul va bien con bufanda roja = sounds incomplete or unnatural in normal Spanish

So in ordinary speech, you would normally keep el and la.

You would change the articles, noun, adjectives, and verb as needed:

• Los jerséis azules van bien con las bufandas rojas.

Breakdown:

• el → los
• jersey → jerséis
• azul → azules
• va → van
• la → las
• bufanda → bufandas
• roja → rojas

This is a good example of how agreement works across the whole sentence.
