In die supermark kyk ons eers na die vrugte.

Afrikaans usually follows the verb-second rule in main clauses. That means the finite verb must come in the second position.

So here:

• In die supermark = first position
• kyk = second position
• ons = comes after the verb

That is why kyk ons is correct after the opening phrase.

A very common pattern is:

• Ons kyk eers na die vrugte.
• In die supermark kyk ons eers na die vrugte.

When you move another element to the front, the verb still stays second.

In this sentence, kyk na means look at.

So:

• kyk = look
• kyk na = look at

You usually need na when you say what someone is looking at:

• Ek kyk na die boek. = I look at the book.
• Ons kyk na die vrugte. = We look at the fruit.

Without na, kyk can be more general, depending on context.

Eers here means first or first of all.

It shows the order of actions:

• Ons kyk eers na die vrugte. = We first look at the fruit.

In other contexts, eers can also have meanings like only later, depending on the sentence. But in this sentence, the natural meaning is first.

Die is the Afrikaans definite article, meaning the.

It is used for:

• singular nouns
• plural nouns

So both of these are correct:

• die supermark = the supermarket
• die vrugte = the fruit / the fruits

Unlike English, Afrikaans does not change the definite article for number. It is always die.

Vrugte is plural.

• vrug = fruit, a fruit
• vrugte = fruits

In many contexts, English uses fruit as a mass noun, but Afrikaans often uses vrugte when talking about fruit in general, especially in a supermarket context.

So die vrugte is very natural here.

Because In die supermark has been placed at the beginning of the sentence.

In a normal basic statement, you might say:

• Ons kyk eers na die vrugte.

But once you start with another element, such as In die supermark, the verb must come second:

• In die supermark kyk ons eers na die vrugte.

So ons is not disappearing or changing role. It is still the subject, but it moves after the verb because of normal Afrikaans word order.

Yes, you can, but the emphasis changes slightly.

• In die supermark kyk ons eers na die vrugte.
  This highlights in the supermarket a bit more.

• Ons kyk eers na die vrugte in die supermark.
  This starts more neutrally with ons.

Both are grammatical. The first version is especially good if you want to set the scene first.

It can mean both, depending on context.

• kyk na die vrugte = look at the fruit
• kyk televisie or kyk TV = watch television

In your sentence, because of na die vrugte, the meaning is clearly look at.

Afrikaans often uses prepositions differently from English.

English says:

• look at

Afrikaans says:

• kyk na

So na is the preposition that goes with kyk when you mention the object being looked at.

This is something learners usually just memorize as a set expression:

• kyk na = look at

A useful breakdown is:

• In die supermark = in the supermarket
• kyk = look
• ons = we
• eers = first
• na die vrugte = at the fruit

So the structure is:

• place/time expression
• verb
• subject
• other information

This is a very common Afrikaans pattern in main clauses when something other than the subject comes first.

Yes, supermark is a normal Afrikaans word for supermarket.

With the definite article, it becomes:

• die supermark = the supermarket

If you mean a supermarket, Afrikaans uses:

• 'n supermark

So:

• in die supermark = in the supermarket
• in 'n supermark = in a supermarket

Sometimes yes, but its position can affect what sounds most natural.

The most natural version here is:

• In die supermark kyk ons eers na die vrugte.

You may also hear:

• Ons kyk eers na die vrugte.

Putting eers close to the verb phrase is very common. It usually comes before the part it affects, here the action of looking at the fruit first.

So for learners, kyk ons eers na die vrugte is a very good pattern to remember.
