'n is the indefinite article, the equivalent of English a or an. So 'n groen hemp means a green shirt.
It is pronounced as a very weak neutral vowel, like uh. It is not pronounced like the letter n. In normal speech it is usually unstressed.
Because they belong to different nouns.
So the sentence has one definite noun phrase and one indefinite noun phrase.
Usually no. Afrikaans verbs are much simpler than English verbs in this way. The verb usually stays the same regardless of the subject.
For example:
So in this sentence, dra does not need a special ending.
Because groen is one of the adjectives that normally stays unchanged here. Afrikaans adjective forms are not completely regular, so it is best to learn common patterns and examples.
In this sentence, groen is simply the correct form before hemp:
So the learner should treat groen as unchanged in this kind of phrase.
It can mean either, depending on context. Afrikaans often uses the simple present where English might use either the simple present or the present continuous.
So Die ondersteuner dra 'n groen hemp can be understood as:
Usually the situation tells you which is more natural.
One natural plural version is:
Die ondersteuners dra groen hemde.
That means The supporters are wearing green shirts or The supporters wear green shirts.
Notice the changes:
Also, if you mean an indefinite plural, Afrikaans usually does not use a plural form of 'n.
