Learn Turkish: Bu elma büyük ve lezzetli. - This apple is big and delicious.

ve simply means "and". Just like in English, you can use it to connect two adjectives that describe the same thing. Here, it connects büyük (big) and lezzetli (delicious) to describe the apple.

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

In Turkish, you often don't need a word for "is" when talking about "he", "she", "it", or "this". Just putting the subject (bu elma) and the adjectives (büyük ve lezzetli) together is enough to mean "This apple is big and delicious."

Is the -li at the end of lezzetli a suffix?

Yes! The base word is lezzet, which means "flavor" or "taste". Adding the suffix -li turns it into an adjective meaning "with flavor" or "delicious".

Do I always need to use ve to connect two adjectives?

Not always. You could just use a comma and say Bu elma büyük, lezzetli. However, using ve (and) makes the sentence sound smoother and more complete, exactly like in English.
