Dataverlies is sleg.

Afrikaans, like Dutch and German, very often forms compound nouns by joining words together.

So:

• data = data
• verlies = loss

Together, dataverlies means data loss.

In English, we usually write data loss as two words, but in Afrikaans it is natural to write it as one compound noun.

Afrikaans often leaves out an article when talking about something in a general or abstract way.

So Dataverlies is sleg means Data loss is bad in a general sense.

If you were talking about a specific case of data loss, you could use die:

• Die dataverlies is sleg. = The data loss is bad.

But in a general statement, no article is perfectly normal.

Mostly yes in this kind of sentence. Is is the Afrikaans present-tense form of to be.

A very useful thing for English speakers is that Afrikaans does not change this verb the way English does. You use is with all persons:

• Ek is = I am
• Jy is = you are
• Hy is = he is
• Ons is = we are
• Hulle is = they are

So Afrikaans is simpler here than English.

Because sleg is being used as a predicate adjective, after the verb is.

In Afrikaans:

• After a linking verb like is, adjectives usually stay in their basic form.
• Before a noun, they often take -e.

Compare:

• Dataverlies is sleg. = Data loss is bad.
• Dit is slegte nuus. = It is bad news.

So:

• sleg = used after is
• slegte = often used before a noun

That is a very common pattern in Afrikaans.

Yes, in this simple sentence it is very similar to English:

• Dataverlies = subject
• is = verb
• sleg = complement/adjective

So the structure is:

Subject + verb + adjective

That makes this sentence easy for English speakers.

However, Afrikaans word order can change more in longer sentences, especially when another element comes first. But in this basic statement, it matches English nicely.

A rough English-friendly pronunciation would be:

DAH-tah-fur-LEES is slekh

A few notes:

• data in Afrikaans is usually pronounced with a clear a sound, not like English day-ta.
• verlies has the stress on the second part: ver-LEES
• g in sleg is the guttural Afrikaans g, made at the back of the throat. English does not really have this exact sound.

If you cannot make the Afrikaans g yet, a rough kh sound is a decent beginner approximation.

Usually yes in a sentence like this. Sleg often means bad, poor, or not good.

Examples:

• Die weer is sleg. = The weather is bad.
• Hy voel sleg. = He feels bad.
• Dataverlies is sleg. = Data loss is bad.

So sleg is a very useful everyday adjective.

Yes, you could, and it would be understandable.

• dataverlies = data loss
• verlies van data = loss of data

Afrikaans often prefers compact compound nouns, so dataverlies sounds neat and natural, especially in technical or formal contexts. But verlies van data is also grammatically fine.

No. Unlike German, Afrikaans does not capitalize all nouns.

So normally you write:

• dataverlies
• data
• verlies

In your sentence, Dataverlies has a capital letter only because it is at the beginning of the sentence.

Yes. That means Data loss is very bad.

Here:

• baie = very / a lot

So you can strengthen the sentence like this:

• Dataverlies is sleg. = Data loss is bad.
• Dataverlies is baie sleg. = Data loss is very bad.

That is a very natural way to add emphasis in Afrikaans.
