A bit about the use of want and omdat:
Want ('because') can never be at the beginning of a sentence, only at the beginning of a subsequent main clause:
Ik draag een jas, want het is koud.
Omdat (also 'because') is more flexible:
Omdat het oud is, is het boek duur. Het boek is duur, omdat het oud is.
This dates back to the Norman conquest of England in 1066, when the French speaking aristocracy were the only people wealthy enough to eat expensive meat, and so their words of French origin (e.g. boeuf --> beef / porc --> pork) were most commonly used to refer to the already prepared meat. The poorer, English speaking peasants, however, would be the ones raising the animals, and so would refer to the living animals with their words of Anglo-Saxon (Germanic) origin.
