Co-ordinating conjunction - Nevenschikkend voegwoord

If a conjunction joins two main clauses, it is a co-ordinating conjunction. Or, to argue the other way, if you use a co-ordinating conjunction, the sentence structure in both clauses is the same. The most common co-ordinating conjunctions are:

dus so
en and
maar but
of or
want for

en
Karin werkt in een boekwinkel. Simone studeert medicijnen.
Karin werkt in een boekwinkel en Simone studeert medicijnen.
Karin works in a book shop and Simone studies medicine.
maar
Ik kom uit Colchester in Engeland. Ik studeer in Hull.
Ik kom uit Colchester in Engeland, maar ik studeer in Hull.
I am from Colchester in England but I study in Hull.

In these examples, the sentence structure in both main clauses is the same, which means that the finite verb is in second position and that the subject comes first. Note that in writing dus, maar and want tend to be preceded by a comma, but en and of do not.
