isteyeceğimiz
"İsteyeceğimiz" means "that we will want" in English.
In this sentence, 'yiyeceğimiz' is used to describe the dinner that 'we will eat', combining the future tense marker 'eceğiz' with the verb root 'yemek' (to eat) and the relative pronoun marker to indicate possession or relation.
Bu akşam yiyeceğimiz yemeği sen mi hazırlıyorsun yoksa dışarı mı çıkacağız?
Are you preparing the dinner we will eat tonight or are we going out?
Here, 'isteyeceğimiz' is from the verb 'istemek' (to desire/request). It is in the future tense (we will request) and indicates possession or relationship to 'the report' that is mentioned.
Görüşme sonrası isteyeceğimiz raporu hazırlamaları için yeterli süre sağlayacağız.
We will provide sufficient time for them to prepare the report we will request after the meeting.
In this example, 'isteyeceğimiz' signifies the permissions that 'we will request' for the purpose of vacation, again showing the use of the future tense and possessive structure.
