Questions & Answers about درسِ هفتم سخت نیست.
How is the word for "seventh" formed in this sentence?
You take the regular number هفت (haft, meaning seven) and add the suffix -om to make هفتم (haftom). This is the standard way to create Type 1 ordinal numbers in Farsi.
Why do we say درسِ هفتم instead of putting the number first like in English?
Ordinal numbers ending in -om behave exactly like normal descriptive adjectives in Farsi. This means they must come after the noun they describe, and they must be linked to it with the invisible Ezafe vowel (-e). Literally, it reads as "lesson-of seventh" (dars-e haftom).
Is there a way to say "the seventh lesson" by putting "seventh" first?
Yes! Farsi has a second type of ordinal number that ends in -omin. If you use هفتمین (haftomin), it goes before the noun and you drop the Ezafe. So, you could also say هفتمین درس (haftomin dars). Both versions are perfectly natural and mean the same thing.
I remember that "is" is often attached to a word as a suffix. Why is "is not" (نیست) a separate word here?
While the positive "is" is often written as the suffix است (ast) attached to the previous word, the negative form نیست (nist) is a strong, independent word. It always stands completely on its own at the very end of the sentence.
