Learn Turkish: Yarın şehri gezmeye gideceğiz. - We will go to visit the city tomorrow.

This word features two consonant changes! First, the root git ends in a hard consonant (t). When we add the future suffix -ecek, the t softens to a d, making gidecek. Then, we add the personal ending for 'we', which is -iz. Since -ecek ends in a k and is followed by a vowel, the k softens into a ğ (soft g). Put it all together: git + ecek + iz = gideceğiz.

Why is 'the city' written as şehri instead of şehiri?

The base word for city is şehir. Since we are going to visit 'the' specific city, we need the accusative case ending -i to point directly at it. However, şehir is one of a few common Turkish words that drop their second vowel when a suffix starting with a vowel is attached. So, şehir + -i shrinks into şehri.

What is the suffix on gezmeye, and why not just say gezmek?

To say you are going somewhere 'to do' something, Turkish uses the short infinitive (-me or -ma) plus the dative case (-e or -a). Here, we take gez (tour/stroll), add -me to make it a noun ('touring'), and then add the dative -e with a buffer y. It literally translates to going 'for touring' or 'to touring'.
