Learn Hardcore Turkish: Eminim ki yarın hava güzel olacak. - I am sure that the weather will be nice tomorrow.

Ki acts as a complementizer, much like the English that. It connects the main clause (Eminim – “I am sure”) to the subordinate clause (yarın hava güzel olacak – “tomorrow the weather will be nice”), clarifying the relationship between the two parts.

How is the subject “I” indicated in Eminim even though it isn’t explicitly stated?

Turkish is a pro-drop language, meaning subject pronouns are often omitted because the verb or adjective endings provide that information. In eminim, the ending -im signals first person singular (“I am”), so there’s no need to explicitly include the pronoun “I.”

How is the future tense expressed in "güzel olacak"?

The future tense is formed using the verb olmak (to be) combined with the future tense suffix -acak (or -ecek, based on vowel harmony). In this sentence, olacak translates to “will be,” indicating a prediction about the weather.

Why does the adverb yarın (tomorrow) appear at the beginning of the subordinate clause?

In Turkish, adverbs—especially those indicating time—often come at the beginning of a clause to set the context for the information that follows. Placing yarın first emphasizes when the event is expected to occur and is a common word order practice in Turkish.

Is using ki after expressions of certainty like eminim mandatory?

Not strictly. While ki is often used after expressions of certainty or belief to introduce a subordinate clause, its usage can sometimes be optional. However, including it usually helps make the connection between the clauses clear, which is particularly beneficial for learners.
