Gee my nog 'n minuut; ek maak net my jas vas en sluit die hek.

Yes. Gee my nog 'n minuut is an imperative, meaning Give me another minute.

In Afrikaans, as in English, the subject is usually left out in commands. So:

• Gee my nog 'n minuut = Give me another minute
• not usually Gee jy my nog 'n minuut

If you add jy, it sounds marked or unusual unless you are stressing who should do it.

Because my can be both:

• the object pronoun me
• the possessive my

So in this sentence:

• Gee my nog 'n minuut = Give me another minute
• my jas = my coat

You tell the difference from position:

• after a verb like gee, my is usually me
• before a noun like jas, my is possessive: my

Both are possible in Afrikaans.

• Gee my nog 'n minuut
• Gee vir my nog 'n minuut

The version without vir is very normal and concise. The version with vir is also common, especially in speech, and can sound a bit more explicit or natural depending on the speaker.

So this is not a mistake; it is just one standard way to say it.

Nog has several related meanings, including still, yet, more, and another.

When it comes before 'n plus a singular noun, it often means another / one more:

• nog 'n minuut = another minute
• nog 'n kans = another chance
• nog 'n koffie = another coffee

So although nog can also mean still, here nog 'n minuut clearly means one more minute.

'n is the Afrikaans indefinite article, the equivalent of English a/an.

A few important points:

• It is written as 'n
• It is pronounced very weakly, like a schwa: uh
• It is not stressed
• Even at the beginning of a sentence, it stays lowercase: 'n

So nog 'n minuut sounds roughly like noch uh min-uut.

Because vasmaak is a separable verb.

The full dictionary form is vasmaak, but in a main clause the conjugated verb moves forward and the particle vas goes to the end of the verbal part:

• Ek maak my jas vas

This is very common in Afrikaans and similar to separable verbs in Dutch and German.

Compare:

• main clause: Ek maak my jas vas
• infinitive: om my jas vas te maak
• subordinate clause: dat ek my jas vasmaak

So the separation in the sentence is completely normal.

It means fasten my coat/jacket.

Depending on the coat, that could mean:

• button it up
• zip it up
• tie it closed
• fasten it securely

The idea of vas is firm / fixed / secure / closed. So iets vasmaak often means to fasten or secure something.

Afrikaans usually uses the simple present for actions happening עכשיו—sorry, for actions happening now as well.

So:

• Ek maak my jas vas en sluit die hek can naturally mean
• I’m fastening my coat and closing the gate

You do not need a special continuous form the way English often does.

If you want to emphasize the ongoing nature, Afrikaans can use other constructions, for example:

• Ek is besig om my jas vas te maak
• Ek is besig om die hek te sluit

But in everyday speech, the simple present is often enough.

Net here means just.

So:

• ek maak net my jas vas en sluit die hek

means something like:

• I’m just fastening my coat and closing the gate

It helps make the delay sound small and temporary. It often softens what you are saying, much like English just.

Most basically, sluit means close/shut.

So sluit die hek is most naturally understood as close/shut the gate. In some contexts, it can also carry the idea of securing it, and English translations sometimes choose lock if that fits the situation.

If someone specifically wants to make the idea of locking unmistakable, they may use a more explicit expression depending on context.

Because the same subject continues across both verbs.

• ek maak net my jas vas en sluit die hek

means:

• I fasten my coat and close the gate

Afrikaans does not need to repeat ek before the second verb when the subject is still the same. English works the same way:

• I’m getting my coat and closing the gate not necessarily
• I’m getting my coat and I’m closing the gate

You could repeat ek, but it would usually sound more emphatic or heavier.

The semicolon links two closely related main clauses:

• Gee my nog 'n minuut
• ek maak net my jas vas en sluit die hek

The second clause explains or justifies the first one, so a semicolon fits well in careful writing.

A full stop would also be possible:

• Gee my nog 'n minuut. Ek maak net my jas vas en sluit die hek.

In speech, it would usually just sound like a pause.
