Questions & Answers about Gezegenin atmosferi çok sıcak olurdu.
Why is it olurdu here instead of oldu or olacaktı?
olurdu is made of the verb olmak (to be/become), the aorist suffix -ur, and the past tense suffix -du. This combination is used for hypothetical situations, translating perfectly to "would be". oldu is simple past ("it was" or "it became"), while olacaktı means "it was going to be".
How does the phrase Gezegenin atmosferi work?
It uses the genitive-possessive structure to show ownership. Gezegen (planet) gets the genitive suffix -in to mean "the planet's". Then, atmosfer gets the 3rd-person possessive suffix -i to link it back, literally functioning as "the planet's its atmosphere".
Why is the possessive suffix on atmosfer just -i and not -si?
The 3rd-person possessive suffix uses the buffer letter s only when the noun ends in a vowel (for example, araba becomes arabası). Because atmosfer ends in the consonant r, it attaches the vowel -i directly without needing a buffer.
Could we just say çok sıcak olur without the -du suffix?
