Die vakbondfooi en inkomstebelasting is op die salarisstrokie.

Because in Afrikaans, the present tense form is is used with both singular and plural subjects.

So:

• Die fooi is ... = The fee is ...
• Die fooie is ... = The fees are ...
• Die vakbondfooi en inkomstebelasting is ... = The union fee and income tax are ...

Unlike English, Afrikaans does not change is to a separate plural form like are.

A single die can cover both nouns in a pair joined by en.

So:

• die vakbondfooi en inkomstebelasting = the union fee and income tax

This is normal and natural. You could also say:

• die vakbondfooi en die inkomstebelasting

That version is also correct, but it sounds a bit more explicitly separate or balanced. In many everyday sentences, one die is enough.

Die is the definite article in Afrikaans, usually meaning the.

In this sentence:

• die vakbondfooi = the union fee
• die salarisstrokie = the payslip

Afrikaans uses die for both singular and plural nouns, so it is simpler than English in that way.

Afrikaans, like Dutch and German, very often forms compound nouns by writing them as a single word.

So:

• vakbond
  • fooi → vakbondfooi
• inkomste
  • belasting → inkomstebelasting
• salaris
  • strokie → salarisstrokie

This is extremely common in Afrikaans. Where English might write two words, Afrikaans often prefers one compound word.

Here is the structure:

• vakbondfooi

  • vakbond = trade union / labor union
  • fooi = fee
  • so vakbondfooi = union fee

• inkomstebelasting

  • inkomste = income
  • belasting = tax
  • so inkomstebelasting = income tax

• salarisstrokie

  • salaris = salary
  • strokie = slip / little strip
  • so salarisstrokie = salary slip / payslip

Op usually means on.

With documents or screens, Afrikaans often uses op to mean on, in the sense of shown on, written on, or appearing on something.

So:

• op die salarisstrokie = on the payslip
• op die rekening = on the bill/account
• op die lys = on the list

This is very similar to English usage.

The sentence follows normal Afrikaans main-clause word order:

Subject + verb + rest

• Die vakbondfooi en inkomstebelasting = subject
• is = verb
• op die salarisstrokie = prepositional phrase

So the pattern is:

The union fee and income tax + are + on the payslip

This is straightforward declarative word order.

Yes, salarisstrokie is a normal and understandable word for payslip or pay slip.

You may also come across:

• betaalstrokie

Both refer to the slip/document that shows pay and deductions. The exact preferred word can vary by region or context.

Because the first word ends in s and the second word begins with st-, the compound keeps both sounds in spelling:

• salaris
  • strokie → salarisstrokie

This kind of doubled consonant at the joining point is normal in compounds. It is not a special grammar rule for this sentence only; it just reflects how the two parts join together.

Yes. Strokie comes from strook, meaning strip or slip, and -ie is a very common Afrikaans diminutive ending.

So strokie literally means something like little slip or small strip.

In practice, though, salarisstrokie is just the standard everyday word for payslip. You do not need to think of it as especially “cute” or “small” in meaning here.

Yes. In good English, the natural translation would use are:

• The union fee and income tax are on the payslip.

That is because English changes the verb for plural subjects, while Afrikaans does not do that here. So the grammar differs between the two languages even though the meaning is the same.
