Ek skil die ui stadig, want my oë raak gou nat.

No. In Afrikaans, want is a conjunction meaning because.

So:

• want my oë raak gou nat = because my eyes get wet quickly / because my eyes water easily

If you want to say English want as a verb, Afrikaans usually uses wil:

• Ek wil water hê = I want water

So want is a very important false friend for English speakers.

Here, skil is the verb to peel.

• Ek skil die ui = I peel the onion

You may also see skil as a noun meaning peel / skin, but in this sentence it is clearly a verb because it comes after Ek.

Die means the, and 'n means a / an.

So:

• die ui = the onion
• 'n ui = an onion

This sentence uses die ui because it refers to a specific onion, not just any onion.

Stadig means slowly.

In a simple Afrikaans main clause, an adverb like stadig often comes after the object:

• Ek skil die ui stadig

That word order is very natural. It is similar to saying:

• I peel the onion slowly

Afrikaans word order is flexible in some cases, but verb + object + adverb is a very common and natural pattern.

Because want is a coordinating conjunction. After want, Afrikaans normally keeps normal main-clause word order.

So you get:

• want my oë raak gou nat

not:

• want my oë gou nat raak

Compare that with omdat meaning because, which does send the verb to the end:

• ... omdat my oë gou nat raak

So a useful contrast is:

• want
  • normal word order
• omdat
  • verb at the end

Here, raak means become or get.

So:

• my oë raak nat = my eyes get wet

It does not mean touch here.

This use of raak is very common with adjectives:

• raak moeg = get tired
• raak kwaad = get angry
• raak nat = get wet

Gou often means quickly, soon, or easily, depending on context.

In this sentence, gou suggests that the eyes become wet quickly / easily when peeling onions.

So a natural sense is:

• my oë raak gou nat = my eyes get wet easily / my eyes start watering quickly

It is not exactly the same as vinnig:

• vinnig focuses more on speed
• gou often sounds more like soon or readily / easily

Here gou is the more natural choice.

Oë is the plural of oog, which means eye.

• oog = eye
• oë = eyes

The two dots, called a diaeresis or trema, show that the vowels are pronounced separately rather than forming one single vowel sound.

So oë is not pronounced as one simple vowel unit. The marking helps the reader see that the word has two syllabic parts.

Because nat comes after raak and works as a predicate adjective.

In Afrikaans, adjectives used after verbs like is, word, or raak usually stay in their basic form:

• Die vloer is nat = The floor is wet
• My oë raak nat = My eyes get wet

So nat does not need an extra ending here.

Yes, it is natural. It sounds like straightforward everyday Afrikaans.

A speaker might also say something a bit more idiomatic, such as:

• Ek skil die ui stadig, want my oë traan gou.

Here traan means tear up / water.

But your original sentence is perfectly good Afrikaans and very understandable.

Those are two of the harder parts for English speakers.

A rough guide:

• ui in die ui has no exact English equivalent. It is a rounded diphthong, and many learners need practice with it.
• oë should be pronounced with the vowels separated, because of the two dots.

A practical learner tip:

• learn ui as a whole sound by imitation
• remember that oë is plural of oog and has a clearly separated vowel sequence

The rest is more straightforward:

• Ek = like eck
• skil = roughly skil
• stadig = roughly staa-dikh or staa-dukh, depending on accent
• want = like vunt
• raak = like rahk
• gou = roughly khow / ghow with an Afrikaans g

If you want, I can also break the whole sentence into a slow pronunciation guide syllable by syllable.
