Hy erken dat hy moeg is.

Here is the structure:

• Hy = he
• erken = admits / acknowledges
• dat = that
• hy = he
• moeg = tired
• is = is

So the sentence has:

• a main clause: Hy erken
• a subordinate clause: dat hy moeg is

Because there are really two clauses here, and each clause needs its own subject.

• Hy erken = He admits
• dat hy moeg is = that he is tired

The same person is meant in both clauses, but Afrikaans still repeats hy, just like English repeats he in He admits that he is tired.

Erken is a verb. It means to admit, to acknowledge, or to recognize, depending on context.

In this sentence, it means to admit.

A useful thing to know is that Afrikaans verbs usually do not change form for different subjects in the present tense:

• Ek erken = I admit
• Hy erken = He admits
• Ons erken = We admit

So unlike English, Afrikaans does not add an extra -s for he.

Dat introduces a subordinate clause, like English that.

So:

• Hy erken = He admits
• dat hy moeg is = that he is tired

It connects the second idea to the first one. After verbs like erken, weet, dink, and sê, Afrikaans often uses dat to introduce what is being admitted, known, thought, or said.

Because dat hy moeg is is a subordinate clause, and in Afrikaans the finite verb normally goes to the end of that kind of clause.

Compare:

• main clause: Hy is moeg.
• subordinate clause: dat hy moeg is

This is one of the most important word-order patterns in Afrikaans.

No, not in standard Afrikaans.

After dat, the normal order is:

• dat + subject + rest + finite verb

So the correct form is:

• dat hy moeg is

Not:

• dat hy is moeg

Moeg is an adjective meaning tired.

In this sentence, it comes after the subject and works with is:

• hy moeg is = he is tired

Afrikaans adjectives used after a linking verb like is usually do not change form. So moeg stays moeg.

Yes. Is is the present-tense form of the verb wees.

So:

• wees = to be
• is = is / am / are in certain present-tense uses, depending on the subject and construction

In this sentence, is links hy and moeg.

Sometimes, especially in less formal speech, Afrikaans may leave out dat after certain verbs. But for learners, it is best to keep it until you are comfortable with the pattern.

So this sentence is very safe and standard:

• Hy erken dat hy moeg is.

If dat is omitted in informal usage, the word order can still follow subordinate-clause patterns depending on the construction, so it is better not to guess too early as a learner.

The pattern is:

• Main clause: Subject + verb
• Subordinate clause after dat: dat + subject + complement + verb

So here:

• Hy = subject
• erken = main verb
• dat = introduces subordinate clause
• hy = subject of subordinate clause
• moeg = complement
• is = verb at the end

A simple formula for this sentence is:

Hy erken + dat + hy + moeg + is

A common negative version would be:

• Hy erken dat hy nie moeg is nie.

Afrikaans usually uses double negation with nie ... nie.

Inside the subordinate clause:

• hy is moeg → hy is nie moeg nie
• after dat: dat hy nie moeg is nie

You could also negate the main clause instead:

• Hy erken nie dat hy moeg is nie.

That means He does not admit that he is tired. The place of nie depends on what exactly you are negating.
