Die inventaris wys of ons verhuisdose opstapel al dan nie.

It means whether or not.

So:

• of = whether / if
• al dan nie = or not

Together, of ons verhuisdose opstapel al dan nie means whether we stack the moving boxes or not.

This is a very common Afrikaans pattern:

• Ek weet nie of hy kom al dan nie. = I don’t know whether he is coming or not.

You will often see of and al dan nie working as a pair.

Because of means whether/if in the sense of uncertainty or indirect questions.

In this sentence, the inventory shows whether something is true. That is why Afrikaans uses of.

Compare:

• Ek weet nie of hy kom nie. = I don’t know if/whether he is coming.
• As hy kom, begin ons. = If he comes, we begin.

So:

• of = whether / if in reported or indirect-question meaning
• as = if for conditionals

Wys means shows.

The verb is wys = to show.

In this sentence:

• Die inventaris wys ... = The inventory shows ...

Afrikaans verbs usually do not change much according to the subject, so wys stays the same:

• ek wys
• jy wys
• ons wys
• hulle wys

That is simpler than English, where you get show but shows with he/she/it.

Because the part after of is a subordinate clause, and Afrikaans normally sends the verb to the end in subordinate clauses.

Main clause:

• Die inventaris wys ...

Subordinate clause:

• of ons verhuisdose opstapel al dan nie

So the structure is roughly:

• of
  • subject + object + verb + al dan nie

This is very typical Afrikaans word order.

Compare:

• Ek weet dat sy hard werk. = I know that she works hard.
• Ons vra of hulle môre kom. = We ask whether they are coming tomorrow.

Yes, opstapel is one word.

It means to stack or to pile up.

It is built from:

• op = up
• stapel = stack / pile

So verhuisdose opstapel means to stack moving boxes.

Depending on context, English could translate it as:

• stack
• stack up
• pile up

Verhuisdose is the plural of verhuisdoos and means moving boxes.

It is a compound noun:

• verhuis = move / moving house
• doos = box

So:

• verhuisdoos = moving box
• verhuisdose = moving boxes

Afrikaans, like Dutch and German, often joins nouns together into one word.

Examples:

• huisdeur = house door / front door
• boekrak = bookshelf
• verhuisdoos = moving box

Because doos has an irregular-looking plural pattern:

• doos → dose

This is just the normal plural form for that word in Afrikaans.

So:

• singular: 'n verhuisdoos
• plural: verhuisdose

A learner usually just has to memorize this plural.

Here it functions like we, because it is the subject of the clause:

• of ons verhuisdose opstapel al dan nie

That means:

• whether we stack moving boxes or not

However, in natural English, you would usually say our moving boxes, because English often prefers a possessive there.

Afrikaans does not always need to make possession explicit in the same way English does. Depending on context, ons verhuisdose can be understood as the moving boxes we are dealing with / our moving boxes.

So grammatically ons is the subject we, not the possessive our.

The key is the sentence structure.

In:

• of ons verhuisdose opstapel al dan nie

the word order is:

• ons = subject
• verhuisdose = object
• opstapel = verb

So it parses as:

• whether we stack moving boxes or not

If ons were possessive, Afrikaans would usually need a clearer structure, and the clause would not fit the normal subject-object-verb pattern as neatly.

So the most natural reading is:

• ons = we

Afrikaans does not use do-support the way English does.

English sometimes uses do for questions, negatives, or emphasis:

• Do we stack the boxes?
• We do stack the boxes.

Afrikaans usually does not add a separate helping verb for that.

So Afrikaans simply says:

• ons stapel die dose op or here, in the subordinate clause:
• of ons verhuisdose opstapel al dan nie

That is normal Afrikaans grammar.

Yes.

• die = the
• inventaris = inventory

So Die inventaris means The inventory.

Afrikaans uses die for the with both singular and plural nouns:

• die boek = the book
• die boeke = the books

Yes, but the meaning would be slightly less explicit.

For example:

• Die inventaris wys of ons verhuisdose opstapel.

This can still mean The inventory shows whether we stack the moving boxes, but al dan nie makes the or not idea fully clear.

So:

• of ... al dan nie = clear, complete whether or not
• of ... alone = often acceptable, but less explicit

The structure is:

• Die inventaris = subject
• wys = main verb
• of ons verhuisdose opstapel al dan nie = subordinate clause functioning as the object/content of shows

So literally:

• The inventory shows [whether we stack moving boxes or not].

This is a useful pattern to learn:

• main clause first
• then a clause introduced by of
• verb at the end of that clause

It is a very common Afrikaans sentence type.
