Morgen licht de docent toe waarom sommige antwoorden beter zijn dan andere.

Dutch is a verb-second (V2) language in main clauses. That means the finite verb must be in the second position.

So when Morgen is placed first for emphasis or time-setting, the verb must come next:

• Morgen licht de docent toe ...

If you started with the subject instead, you would get:

• De docent licht morgen toe ...

Both are correct, but the word order changes because of the V2 rule.

Licht ... toe is the split form of the separable verb toelichten, which means to explain, to clarify, or to elaborate on.

In a main clause, separable verbs often split:

• toelichten → licht ... toe

So:

• De docent licht toe = The teacher explains / clarifies

This is very common in Dutch.

Because toelichten is a separable verb.

In a normal main clause, the verb stem is conjugated and moved to the usual finite-verb position, while the prefix goes to the end of the clause:

• infinitive: toelichten
• present tense: ik licht toe, hij licht toe

In other structures, it may stay together:

• De docent wil het morgen toelichten.
• Omdat de docent het morgen toelicht.

So the split depends on the sentence structure.

Dutch often uses the present tense to talk about the future when the time is already clear from context.

Here, Morgen already tells you the action is in the future, so Dutch does not need a separate future form.

That is why:

• Morgen licht de docent toe ...

is perfectly natural.

You could also say:

• Morgen zal de docent toelichten ...

But that is often a bit more formal, more explicit, or sometimes less natural in everyday speech.

This is a subordinate clause introduced by waarom.

In Dutch subordinate clauses, the conjugated verb usually goes toward the end. That is why you get:

• waarom sommige antwoorden beter zijn dan andere

not:

• waarom sommige antwoorden zijn beter dan andere

So the order is:

• waarom
  • subject + other parts + verb

Here:

• waarom = why
• sommige antwoorden = some answers
• beter = better
• zijn = are
• dan andere = than others

Sommige is the determiner meaning some before a noun:

• sommige antwoorden = some answers

Sommigen is a pronoun meaning some people or some of them, and it is not used before a noun in this way.

So:

• sommige antwoorden = correct
• sommigen antwoorden = incorrect here

Dutch often leaves out a noun when it is already obvious from context.

So:

• dan andere

really means:

• dan andere antwoorden

This is just like English than others, where answers is understood.

So the full idea is:

• some answers are better than other answers
• shortened to: some answers are better than others

Here andere stands for other answers, so it refers to things, not people.

In Dutch:

• anderen usually means other people
• andere can mean other ones/things or can go before a noun

So here:

• dan andere = than others / than other ones
• dan anderen would sound like than other people, which does not fit

Docent usually means teacher or lecturer, often in secondary education, college, or university contexts, depending on the situation.

It does not always match English teacher and lecturer perfectly. In many contexts, docent is a general word for someone who teaches a subject.

Also, de is the article for this noun because docent is a de-word.

Yes, that is grammatically correct.

• Morgen licht de docent toe waarom ...
• Morgen zal de docent toelichten waarom ...

Both mean roughly the same thing.

The version with the simple present is usually very natural in Dutch when the future time is already clear. The version with zal can sound a bit more formal, planned, or explicitly future-oriented.
