Questions & Answers about این جادهها خطرناک است.
Why does the sentence use the singular verb است instead of a plural verb for "these roads"?
In Farsi, inanimate subjects (things that are not alive, like roads) usually take a singular verb, even when they are plural. Since جادهها is plural but not alive, we use the singular است (is) rather than the plural هستند (are).
Why is it این instead of a plural word for "these"?
When words like این (this) and آن (that) are used as adjectives right before a noun, they never take a plural marker. You just make the noun plural. So این جادهها literally looks like "this roads," but it correctly means "these roads."
How do you break down the word خطرناک?
It is made of the noun خطر (danger) plus the suffix ناک, which turns a noun into an adjective meaning "full of" or "causing." So خطرناک means "dangerous."
Should the adjective خطرناک be plural to match "roads"?
No, in Farsi, adjectives do not change to match the noun they describe, whether they come before the noun or after it with a "to be" verb. The adjective stays in its basic dictionary form.
