Learn Turkish: Ormanda vahşi hayvanlar vardır. - There are wild animals in the forest.

Var simply means "there is" or "there are." Adding the factual suffix -dır turns this into a statement of general truth or an objective fact. By saying vardır, you are stating an encyclopedic characteristic about the forest in general, rather than just observing animals you see right at this moment.

Why does ormanda (in the forest) come at the very beginning of the sentence?

In Turkish "there is / there are" sentences, it is standard to set the scene first. The typical word order is to put the location or time first, followed by the subject, and ending with var or yok (or their variations like vardır).

Why do we use the plural hayvanlar here? Doesn't Turkish sometimes use singular words for plurals?

Turkish keeps the noun singular only if you use a specific number (like iki hayvan - two animals) or a quantity word (like çok hayvan - many animals). Since there are no numbers or quantity words in this sentence, we must use the plural suffix -lar to show there are multiple animals.

Why does the factual suffix take the form -dır here, rather than -dir or -dur?
