Learn Turkish: Cüzdan belki cepte, belki başka bir yerde. - The wallet is maybe in the pocket, maybe somewhere else.

In this lesson, you are learning that bir yer means "somewhere" (literally "a place"). Başka means "other" or "else." When you combine them into başka bir yer, it means "somewhere else" or "another place." Finally, the locative suffix -de (in/at) is added to make it "in somewhere else."

Why does "in the pocket" use -te (cepte) but "in a place" uses -de (yerde)?

This is a quick refresher on consonant mutation (often called the FSTKÇŞHP or "ketchup" rule). Because cep (pocket) ends in the hard/voiceless consonant p, the locative suffix -de hardens into -te to match it. The word yer (place) ends in the soft consonant r, so it takes the regular -de.

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

There isn't one! In Turkish, you don't need a specific word for "is" when making basic "A is B" statements in the present tense for the third person (he/she/it). Simply putting the subject (cüzdan) and the location (cepte) together naturally means "the wallet is in the pocket."

Is it normal to repeat belki (maybe) twice in the same sentence?
