Learn Turkish: Mavi pantolon çok uzun. - The blue trousers are very long.

In Turkish, adjectives always go right before the noun they describe, just like in English. So we say mavi pantolon (blue trousers) to modify the noun directly.

"Trousers" is plural in English. Why isn't pantolon plural in Turkish?

In English, words for clothing with two legs (like trousers, pants, or shorts) are treated as plural. In Turkish, a pair of trousers is just one single item, so pantolon stays in the singular form unless you are actually talking about multiple pairs of trousers.

Where is the word for "are" in this sentence?

There isn't a separate word for it here! In Turkish, the "to be" verb (am/is/are) for the "he/she/it" form is often invisible. Saying pantolon çok uzun literally translates to "trousers very long", which naturally means "the trousers are very long".

If I wanted to say "The trousers are very blue", would the word order change?

Yes! You would say Pantolon çok mavi. The adjective mavi (blue) moves to the end of the sentence because it is now the main fact being stated about the subject, rather than sitting next to the noun to form a phrase like "blue trousers".
