Questions & Answers about بعضی از دریاچهها خیلی عمیق هستند.
Why do we say ba'zi az instead of just ba'zi?
Ba'zi means "some", but when you are talking about a portion of a specific group—like "some of the lakes"—you use ba'zi az (literally "some from"). If you just wanted to say "some lakes" in a general, unspecified sense, you would drop the az and just say ba'zi daryāche-hā.
I know daryā means "sea". Is daryāche related to it?
Yes! The suffix -che is a diminutive ending in Farsi, meaning it refers to a smaller version of something. So, daryāche literally means "little sea", which is how Farsi forms the word for "lake".
In this lesson about superlatives, how would I change "very deep" (kheyli amigh) to say "the deepest lakes" using this sentence's vocabulary?
To make a superlative, add -tarin to the adjective to get amigh-tarin (deepest). As you are learning in this lesson, superlative adjectives go before the noun and do not take an Ezafe (the linking "e" sound). So "the deepest lakes" would be amigh-tarin daryāche-hā.
Since lakes are inanimate objects, shouldn't the verb be singular (ast) instead of plural (hastand)?
You are right to remember from earlier lessons that inanimate plural nouns in Farsi usually take a singular verb. However, using a plural verb like hastand is also completely correct. It is often used to emphasize the individual distinct items within a group, rather than treating them as a single collective block.
