Why does bozorg-tarin come before sahra instead of after it?
In Farsi, normal adjectives come after the noun with an Ezafe connector (like sahra-ye bozorg for "the big desert"). However, superlative adjectives ending in -tarin (meaning "-est" or "most") are an exception! They always come before the noun, and you do not use an Ezafe.
How do we build the words for "biggest" and "hottest" here?
You take the simple adjective, like bozorg (big) or garm (hot), and add the suffix -tarin. This is exactly like adding "-est" in English. So, bozorg-tarin means "biggest" and garm-tarin means "hottest".
Does connecting two superlatives with "and" (va) change the grammar rules?
Not at all! When you have two superlatives like bozorg-tarin va garm-tarin (biggest and hottest), they both sit together right before the noun sahra (desert). You still don't need any Ezafe between the adjectives and the noun.
Why is ast (is) at the very end of the sentence?
Farsi is a Subject-Object-Verb language, which means the verb generally goes at the very end. Here, the subject is in (this), the descriptive phrase is bozorg-tarin va garm-tarin sahra, and the verb ast neatly finishes the thought.
