Learn Turkish: Erken gitme, burada bekle. - Do not go early, wait here.

The verb root for "to go" is git-. To tell someone not to do something, we add the negative suffix -me or -ma to the root. Since the vowel in git- is an 'i', vowel harmony rules dictate we use -me, making it gitme ("don't go").

Who are we talking to in this sentence? Is it formal or informal?

This sentence uses the informal, singular "you" (sen). We know this because the verbs gitme and bekle use the base root form (plus the negative suffix for gitme) without any extra personal endings. If you were speaking formally or to multiple people, it would be gitmeyin and bekleyin.

Why does the word for "here" have the suffix -da in burada?

The base word bura roughly means "this place". To say you are at or in a location, you need the locative suffix -da or -de ("at/in/on"). Therefore, burada literally translates to "at this place," which we just translate as "here" in English.

Why doesn't the verb bekle have any endings?
