Both are used. "Daar" is the emphasised form of "er", but "er" has a lot of more uses than just that.
"It is often necessary to include er when the subject is indefinite (i.e. doesn't point to a specific person or object)." (Tips and notes from the skill "er". 2nd tree)
Dankjewel! Ik is net gewoond aan het eenvoudige Afrikaans. Do you know wat "vijf glazen" mean in the following quote? "Omtrent vijf glazen in den nademiddagwacht, zagen wij, Gode lof, het land van de

Thank you very much. Great source for future use. The excerpt is from the journal of Jan van Riebeeck in 1652. What is amazing to me as that I can understand most of it, even though I'm Afrikaans speaking. Groetjes en heel veel dank voor de hulp.
