El venedor de la botiga virtual ven el producte.

Because Catalan normally uses definite articles the same way English uses the.

• el = masculine singular
• la = feminine singular

So in this sentence:

• el venedor = masculine singular
• la botiga = feminine singular
• el producte = masculine singular

If they were plural, you would get:

• els venedors
• les botigues
• els productes

Because de only contracts with el, not with la.

So:

• de + el = del
• de + la = de la

Examples:

• el venedor del supermercat
• el venedor de la botiga virtual

This is a very common pattern in Catalan.

It most naturally describes el venedor.

So the structure is:

• El venedor
  de la botiga virtual
  ven el producte.

In other words, it means the seller belonging to / associated with the online shop is the one selling the product.

This matters because Catalan word order helps show what a phrase modifies. If you moved that phrase, the meaning could shift.

Because in Catalan, adjectives usually come after the noun.

So:

• botiga virtual
• producte virtual
• cotxe nou
• casa gran

That is the normal order. English often puts adjectives before the noun, but Catalan usually does not.

Also, virtual has the same form for masculine and feminine singular:

• botiga virtual
• producte virtual

The plural is virtuals.

Yes. Both are related to the verb vendre meaning to sell.

• ven = sells
• venedor = seller

So they share the same basic idea of selling.

A useful pattern is that Catalan often forms person-nouns with endings like -dor / -dora:

• venedor = male seller
• venedora = female seller

Ven is the 3rd person singular present indicative form of vendre.

So it matches a singular subject like:

• el venedor ven
• la venedora ven
• la botiga ven

In this sentence, the subject is el venedor, so ven means sells.

Because Catalan normally uses a word order very similar to English:

Subject + Verb + Object

Here that is:

• El venedor = subject
• ven = verb
• el producte = object

So the sentence follows the basic Catalan pattern very naturally.

Yes, but the default order is the one shown.

Catalan can move parts of the sentence for emphasis, but that usually makes the sentence feel more marked or changes what sounds like the main topic.

For example, if you move de la botiga virtual, it may start sounding like it describes el producte instead of el venedor.

So for a neutral statement, the original version is the safest and most natural.

You would change the noun and article to the feminine form:

• La venedora de la botiga virtual ven el producte.

Changes:

• el venedor → la venedora

The rest of the sentence stays the same, because:

• botiga was already feminine
• virtual does not change here
• ven still agrees with a singular subject

It is correct and understandable, yes.

But depending on region and style, you may also hear:

• botiga en línia
• botiga online

Botiga virtual is perfectly fine, though it can sound a bit more formal or literal in some contexts.

For many Catalan speakers, v and b are pronounced the same or almost the same.

So venedor usually does not begin with a strong English v sound. It is often closer to a b-like sound.

This is normal in Catalan and is something English speakers often notice early on.

There is some regional variation, but if you pronounce v and b the same in Catalan, that is very common.
