Learn Turkish: Altı yumurta var.

In Turkish, whenever you use a number before a noun to state a quantity, the noun must stay in its singular form. Since we already have the number altı (six), adding a plural ending to yumurta is considered incorrect.

The lesson mentions using tane for counting. Could I say Altı tane yumurta var instead?

Yes, you absolutely can! Adding tane (which roughly translates to 'item' or 'piece') between the number and the noun is very common and sounds perfectly natural in everyday Turkish. Both Altı yumurta var and Altı tane yumurta var mean exactly the same thing.

Why do we use var here instead of a plural verb for 'are'?

Var is a special word that means 'there is' or 'there are' to show that something exists. It never changes its form based on whether the subject is singular or plural. Whether there is one egg or six eggs, you just use var.

Why is var placed at the very end of the sentence?

Turkish naturally puts its main action or state at the end of a sentence. Words that indicate existence, like var (there is/are) and its opposite yok (there is/are not), almost always go at the very end.
