Future statements (-(y)AcAğI)

Future Noun Clauses

To say that something will happen, Turkish transforms the future tense verb into a noun clause. Instead of using a connecting word like "that," attach suffixes directly to the verb stem:

1. Add the future suffix -(y)acak / -(y)ecek.
2. Add a possessive suffix to indicate who or what will perform the action. Because possessive suffixes start with a vowel, consonant mutation changes the k in the future suffix to ğ (-(y)acağ- / -(y)eceğ-).
3. Add the case marker required by the main verb. These clauses often act as direct objects, so they usually take the accusative case (remember the buffer n after a third-person possessive suffix).

yağ- (to rain) + -acak (future) + -ı (its) + -nı (accusative) = yağacağını (that it will rain)

Because the action is treated grammatically like a possessed object, the subject of the clause usually takes the genitive suffix. For example, "humidity" (nem) becomes nemin ("humidity's").

Negative Future Clauses

To state that something will not happen, insert the negative suffix (-ma / -me) right after the verb stem. You will always need the buffer letter y before the future suffix.

ol- (to be) + -ma (negative) + -y- (buffer) + -acak (future) + -ı (its) + -nı (accusative) = olmayacağını (that it will not be)

Making Predictions

This noun clause structure is commonly used with verbs related to communication and thought, such as tahmin etmek (to predict), düşünmek (to think), duymak (to hear), and öğrenmek (to learn).
