Die inventaris bevat die eenheidsnommer.

No. In this sentence, die is the Afrikaans definite article, meaning the.

So:

• die inventaris = the inventory
• die eenheidsnommer = the unit number

It is usually pronounced roughly like dee, not like English die.

Because both nouns are definite.

Afrikaans uses die for the before nouns, so you get:

• die inventaris = the inventory
• die eenheidsnommer = the unit number

This is completely normal. English does the same thing: The inventory contains the unit number.

Not in the way an English speaker might expect from languages like German or Dutch.

Afrikaans uses die as the definite article for nouns very broadly, including singular and plural nouns. So you do not have to learn different forms for masculine, feminine, or neuter nouns.

That makes Afrikaans simpler than some related languages.

Bevat means contains or includes.

In this sentence, it tells you what the inventory has in it:

• Die inventaris bevat die eenheidsnommer.
• The inventory contains the unit number.

Depending on context, contains is usually the best translation.

Because Afrikaans verbs do not usually change form according to the subject in the present tense.

English:

• I contain
• it contains

Afrikaans:

• ek bevat
• dit bevat
• die inventaris bevat

So bevat stays the same regardless of who or what the subject is.

Because this is a simple main clause with the subject first.

The basic pattern here is:

• Die inventaris = subject
• bevat = verb
• die eenheidsnommer = object

So it follows the familiar subject–verb–object pattern that English speakers expect.

A useful extra point: in Afrikaans main clauses, the finite verb normally comes in the second position. When the subject comes first, the sentence often looks very similar to English.

Because Afrikaans usually writes compound nouns as a single word.

So:

• eenheid = unit
• nommer = number
• eenheidsnommer = unit number

This is very common in Afrikaans. Where English often uses two words, Afrikaans often combines them into one compound noun.

The s is a linking sound/letter used in some Afrikaans compounds.

So this word is built like this:

• eenheid
• linking s
• nommer

This s is not showing possession here, and it is not a separate word. It is just part of how the compound is formed.

Yes, it is a close cognate.

That makes it easy for English speakers to recognize. However, it still behaves like an Afrikaans noun in an Afrikaans sentence, so you should learn it with its article and in context:

• die inventaris

Cognates are helpful, but it is still good to pay attention to spelling and usage.

You would usually use the Afrikaans double negative:

Die inventaris bevat nie die eenheidsnommer nie.

A very common Afrikaans pattern is:

• verb + nie
  • rest of sentence + final nie

So if you are learning Afrikaans sentence structure, this is an important pattern to notice early.

You could, but it is not exactly the same in tone.

• bevat = contains / includes
• het = has

So:

• Die inventaris bevat die eenheidsnommer sounds like the number is included as part of the inventory record or contents.
• Die inventaris het die eenheidsnommer sounds more like the inventory simply has or possesses it.

In many contexts, bevat is the more precise choice.
