Die onderwyser aan wie ek my vraag stuur, antwoord amper dadelik.

Because wie is used for people after a preposition. Here the teacher is a person, and the preposition is aan, so aan wie is the normal choice.

By contrast, with things, Afrikaans usually prefers a waar- form: die tafel waarop die boek lê = the table on which the book lies

So in this sentence, aan wie is right because the reference is to a person.

Because that part is a relative clause, and Afrikaans puts the finite verb at the end of subordinate clauses. So:

• Main clause: Ek stuur my vraag aan die onderwyser.
• Relative clause: aan wie ek my vraag stuur

This verb-final pattern is very common in Afrikaans subordinate clauses.

Afrikaans normally uses commas to mark off subordinate clauses, including relative clauses. So the commas here are mainly showing the structure of the sentence.

This is not exactly the same as English comma usage. In English, commas around a relative clause often suggest extra, non-essential information. In Afrikaans, commas are used more routinely with these clause types.

Because after the relative clause ends, the sentence returns to the main clause, and Afrikaans main clauses usually follow the verb-second pattern. The main clause is:

Die onderwyser antwoord amper dadelik.

The relative clause interrupts that main clause, but once it is finished, the finite verb of the main clause appears in its normal position.

No. Afrikaans verbs usually do not change form according to person or number in the present tense. So the same form is used for:

• ek antwoord = I answer
• jy antwoord = you answer
• hy antwoord = he answers
• ons antwoord = we answer

So die onderwyser antwoord is completely normal.

Because my is the normal possessive form used before a noun: my vraag = my question.

Myne is not used in that position. In Afrikaans, possessive words before nouns are simple:

• my boek
• jou vraag
• sy pen
• ons huis

So my vraag is the correct form.

In standard Afrikaans, aan wie is the best choice here because the verb relationship is stuur ... aan iemand. Some speakers may use vir in everyday speech in certain contexts, but for a sentence like this, aan wie is the clearest and most standard form.

So for learners, it is safest to learn: stuur iets aan iemand and therefore die persoon aan wie ...

Not in careful standard Afrikaans for a person. With a preposition and a person, Afrikaans normally keeps the preposition together with wie:

die onderwyser aan wie ek my vraag stuur

Using wat that way would not be the standard form here. For people, wie is the important relative word after a preposition.

Dadelik means immediately. Amper means almost. Together, amper dadelik means almost immediately.

So amper is modifying dadelik. It does not mean barely here; it means the reply comes very quickly, but not literally instantly.

The core sentence is:

Die onderwyser antwoord amper dadelik.

The middle part, aan wie ek my vraag stuur, is just extra information describing die onderwyser. It tells you which teacher is meant. Seeing that basic frame often makes the whole sentence easier to understand.
