Why does the sentence start with in (this) instead of a word for "these"?
In Farsi, when words like "this" (in) or "that" (ân) are followed directly by a noun, they stay singular. So, you literally say "this lights" (in cherâgh-hâ) instead of "these lights".
How is the plural formed for the word "lights" in this sentence?
By adding the regular plural suffix -hâ. In Farsi, almost any noun can be made plural by simply attaching -hâ to the end. Here, cherâgh (light) becomes cherâgh-hâ (lights).
Why does the sentence use the singular verb ast (is) when talking about multiple lights?
This is a very important rule in Farsi! When a plural subject is inanimate (a thing or an idea, rather than a person or animal), the verb is usually singular. Since "lights" are objects, Farsi uses ast (is) instead of the plural hastand (are).
Why doesn't the adjective jadid (new) get a plural marker too?
Unlike some other languages, adjectives in Farsi do not change form to agree with plural nouns. jadid stays exactly the same whether you are talking about one new light or fifty new lights.
