Learn Turkish: Laleli vazo çok güzel. - The vase with tulips is very beautiful.

The word lale means tulip. By adding the suffix -li (meaning with or containing), it becomes the adjective laleli, which translates to with tulips. Here, it acts as an adjective directly describing the vase.

Why isn't there a buffer 'y' before the suffix, like laleyli?

Unlike case suffixes (such as the dative -e or accusative -i), the adjective-forming suffix -li starts with a consonant. Therefore, it attaches directly to words ending in a vowel without needing a buffer y.

Does laleli vazo mean the vase has actual tulips inside it, or is painted with tulips?

It can mean both! The suffix -li simply means characterized by or containing. Depending on the context, laleli vazo could refer to a vase holding physical tulips, or a vase decorated with a tulip pattern.

Why is there no verb at the end of the sentence to mean 'is'?

In Turkish, the third-person singular 'to be' suffix (-dir or -tir) is often dropped in everyday speech. Ending the sentence with the adjective güzel is perfectly complete and naturally means is beautiful.
