Die posisie kan voltyds of deeltyds wees.

Yes. Die is the Afrikaans definite article, so here it means the.

A useful thing to remember is that Afrikaans uses die for:

• singular nouns: die posisie = the position
• plural nouns: die poste = the positions

Unlike English, Afrikaans does not have different forms like the vs something else depending on gender, and unlike German, nouns are not normally capitalized unless they start the sentence.

Yes, posisie is very close to English position. In this sentence, it most naturally means:

• a job position
• a role
• a post

So Die posisie is a very normal way to say the position in a job-related context.

Because Afrikaans follows the verb-second rule in main clauses. That means the finite verb usually comes early in the sentence, typically in the second main slot.

Here:

• Die posisie = subject
• kan = finite verb / modal verb
• voltyds of deeltyds wees = rest of the predicate

So the structure is very normal Afrikaans:

• Die posisie kan ... wees.

This is similar to Dutch and German word order.

Because kan is a modal verb, and in Afrikaans modal verbs usually send the main verb to the end in an infinitive form.

So:

• kan = can
• wees = be

That gives:

• kan ... wees = can be

This pattern is extremely common:

• Ek kan kom. = I can come.
• Sy kan werk. = She can work.
• Die posisie kan voltyds wees. = The position can be full-time.

Yes. Wees is the infinitive form meaning to be.

In this sentence, after the modal kan, it works like English be:

• kan wees = can be

You will also see other forms related to to be, especially is:

• Dit is goed. = It is good.
• Die posisie is voltyds. = The position is full-time.

So:

• is = is
• wees = be / to be

They mean:

• voltyds = full-time
• deeltyds = part-time

These are common words in work and study contexts.

Examples:

• Ek werk voltyds. = I work full-time.
• Sy studeer deeltyds. = She studies part-time.

In your sentence, they describe what kind of position it can be.

In this sentence, they function like predicate complements after wees, so in English terms they are behaving like adjectives: full-time / part-time.

Afrikaans is often flexible with words of this type, and learners do not usually need to worry too much about forcing a strict adjective/adverb label here. The important thing is that after wees, they describe the posisie:

• Die posisie ... wees → the position can be voltyds or deeltyds

Here of means or.

So:

• voltyds of deeltyds = full-time or part-time

Be careful, because in some contexts of can also correspond to English whether:

• Ek weet nie of hy kom nie. = I don't know whether he is coming.

But in your sentence, it clearly means or.

Yes, but it means something slightly different.

• Die posisie kan voltyds of deeltyds wees.
  = The position can be full-time or part-time.
  This suggests possibility or flexibility.

• Die posisie is voltyds of deeltyds.
  = The position is full-time or part-time.
  This sounds more like a plain statement, but in real life it can feel a bit odd because one specific position is usually one or the other unless you mean the role may be offered in either form.

So kan ... wees is a very natural choice when talking about options.

In a subordinate clause, the modal and infinitive usually move to the end.

Main clause:

• Die posisie kan voltyds of deeltyds wees.

Subordinate clause:

• Ek weet dat die posisie voltyds of deeltyds kan wees.
• Ons hoor dat die posisie deeltyds kan wees.

Notice how kan wees shifts toward the end in the subordinate clause. This is a very useful Afrikaans pattern to learn early.

A rough pronunciation guide is:

• Die ≈ dee
• posisie ≈ po-SEE-see
• kan ≈ kun or kahn depending on accent
• voltyds ≈ FOL-tays
• of ≈ off
• deeltyds ≈ DALE-tays
• wees ≈ vace

So a rough full version would be:

dee po-SEE-see kun FOL-tays off DALE-tays vace

A few pronunciation notes:

• Afrikaans w sounds like English v
• ee is often like a long ay sound
• y in tyds is not like English eye; it is closer to a diphthong that English speakers often approximate badly at first

It is singular: the position.

You can tell from posisie, which is singular.
If it were plural, you would usually have a plural noun, for example:

• Die posisies kan voltyds of deeltyds wees. = The positions can be full-time or part-time.

Notice that die itself does not change, so the noun form is what tells you whether it is singular or plural.

Yes, very common. It sounds natural in job advertisements, HR language, and workplace discussions.

Similar useful sentences are:

• Die posisie is permanent. = The position is permanent.
• Die posisie is tydelik. = The position is temporary.
• Die posisie kan op kantoor of op afstand wees. = The position can be in-office or remote.

So your sentence is a very practical and natural example of job-related Afrikaans.
