Sy praat so eerlik dat almal dadelik sien wanneer iets verkeerd is.

So ... dat is a very common Afrikaans pattern meaning so ... that.

• so eerlik = so honest / so honestly
• dat = that

So the structure links a cause or quality to a result:

• Sy praat so eerlik dat ... = She speaks so honestly that ...

This works much like English:

• Hy is so moeg dat hy aan die slaap raak. = He is so tired that he falls asleep.

Here eerlik functions like an adverb: it describes how she speaks.

In Afrikaans, adjectives and adverbs often have the same form, unlike English, which often adds -ly.

So:

• 'n eerlike mens = an honest person
• Sy praat eerlik = She speaks honestly

That is very normal in Afrikaans. You do not need a special adverb ending like -ly.

Because Afrikaans verbs do not usually change according to the subject in the present tense.

Compare English:

• I speak
• she speaks

Afrikaans:

• Ek praat
• Jy praat
• Sy praat
• Hulle praat

The verb stays the same. This is one of the simpler parts of Afrikaans grammar.

Almal means everyone, everybody, or sometimes all people depending on context.

In this sentence:

• almal sien = everyone sees

It is a very common word and is often used on its own as a subject:

• Almal weet dit. = Everyone knows that.

Dadelik means immediately, at once, or right away.

In the sentence:

• almal dadelik sien = everyone immediately sees

Afrikaans adverbs like dadelik often come before the main verb or in the middle of the clause, depending on the sentence structure. Its position here is natural and idiomatic.

After dat, Afrikaans usually introduces a subordinate clause. In subordinate clauses, the word order often changes, and the verb tends to move toward the end.

However, in this clause, sien is still before the next subordinate clause because wanneer iets verkeerd is belongs to sien.

So the structure is:

• dat
  • subject + adverb + verb + subordinate clause

Breaking it up:

• dat = that
• almal = everyone
• dadelik = immediately
• sien = sees
• wanneer iets verkeerd is = when/whenever something is wrong

So sien comes before the wanneer clause because that whole wanneer part is what people are seeing.

Because wanneer iets verkeerd is is a subordinate clause, and in Afrikaans subordinate clauses, the finite verb usually goes to the end.

So:

• iets is verkeerd = something is wrong
  This is a main clause.

But after wanneer:

• wanneer iets verkeerd is = when something is wrong

This verb-final pattern is very important in Afrikaans and shows up after words like:

• dat = that
• wanneer = when
• omdat = because
• as = if / when

Grammatically, wanneer often means when, but in many contexts it can also feel like whenever.

In this sentence, because it describes a general pattern, English might naturally understand it as:

• when something is wrong
• or whenever something is wrong

So wanneer here has a general, repeated sense, not just one specific moment in time.

Yes, iets verkeerd is a very common combination meaning something wrong.

• iets = something
• verkeerd = wrong

So:

• iets verkeerd is = something is wrong

You can compare:

• Daar is iets verkeerd. = Something is wrong.
• Ek het iets verkeerd gedoen. = I did something wrong.

Here verkeerd is describing iets, but because of the clause structure, the full phrase becomes iets verkeerd is.

Yes. Sy can mean:

• she as a subject pronoun
• his as a possessive word

Examples:

• Sy praat. = She speaks.
• Sy boek is hier. = His book is here.

In your sentence, Sy praat ..., it clearly means she because it is followed by a verb and functions as the subject.

Verkeerd is very flexible. It can mean wrong, incorrect, or incorrectly, depending on the sentence.

Examples:

• Dit is verkeerd. = That is wrong.
• Jy antwoord verkeerd. = You answer incorrectly.
• iets verkeerd = something wrong

So in your sentence, it is part of the idea something is wrong.

Yes, but the meaning would change a bit.

• Sy praat eerlik. = She speaks honestly.

That simply states a fact.

• Sy praat so eerlik dat almal dadelik sien ... = She speaks so honestly that everyone immediately sees ...

This adds a result: her honesty is so noticeable that it causes something else to happen. So so is important if you want the full so ... that meaning.
