Questions & Answers about من از تاریکی اتاق میترسم.
How is the word târiki (darkness) formed here?
It is formed by taking the adjective târik (dark) and adding the suffix -i. This is a standard way in Farsi to turn an adjective into an abstract noun, functioning exactly like the "-ness" suffix in English.
Why do we use the preposition az (from) when the English translation says "afraid of"?
In Farsi, the verb tarsidan (to fear / be afraid) always requires the preposition az. You literally say that you are afraid from something. This is a set verb-preposition pair that you will see every time someone talks about being scared.
How are the words târiki (darkness) and otâq (room) linked together when spoken?
They are connected by the ezafe. Because the abstract noun târiki ends in a vowel (the -i suffix), the ezafe is pronounced as a -ye sound to bridge the words smoothly: târiki-ye otâq (the darkness of the room).
Does the prefix mi- on mitarsam mean I am afraid right now, or that I generally fear the dark room?
It can mean both! The present prefix mi- is used for both ongoing states (present continuous) and general facts (simple present). Without more context, this sentence could mean "I am afraid right now" (while standing in the room) or "I am generally afraid" (as a habit).
