Questions & Answers about Kar yağacaktı ve kayağa gidecektik.
How do the suffixes in yağacaktı create the meaning 'was going to'?
It stacks the future suffix -acak and the past suffix -tı. Combining them as yağ-acak-tı literally means it was in the future of snowing, which translates perfectly to 'it was going to snow'. We use this pattern for things we expected or intended to happen in the past but usually didn't.
Why does gidecektik end with -k for 'we' instead of the usual -iz?
Because the very last suffix on the word is the past tense -ti. When stacking suffixes, the personal ending always matches the final suffix. Since the past tense uses a special set of endings where 'we' is just -k (as you learned with simple past verbs like yaptık), we use -k here too: git-ecek-ti-k.
Why is there a d in gidecektik if the verb root is git-?
This is consonant softening. When the verb root git- (to go) is followed by a suffix starting with a vowel, like the future suffix -ecek, the hard t softens into a d. So it becomes gidecek instead of gitecek.
