Learn Farsi: انگار همسایه‌ی جدید خیلی سر و صدا می‌کند. - It seems the new neighbor is making a lot of noise.

In this sentence, انگار means "it seems that" and expresses an assumption based on real evidence (you can probably hear the noise). When انگار expresses a likely reality or observation, it takes the indicative. If it were a purely hypothetical "as if" (e.g., "he acts as if he were the boss"), you would use the subjunctive.

What is the literal meaning of سر و صدا?

It literally translates to "head and sound" or "head and voice." In Farsi, it is a very common compound noun meaning "noise" or "commotion." It is paired with the light verb کردن (to do/make), giving us سر و صدا می‌کند for "is making noise."

Why is there a ی attached to همسایه?

This is the ezafe connecting the noun همسایه (neighbor) to the adjective جدید (new). Because همسایه ends in a silent ه (which sounds like an 'e'), we must add the consonant ی (y) in writing and pronunciation to link them smoothly: hamsâye-ye jadid.

Could انگار be replaced with گویا in this sentence?

Yes, گویا (gouyâ) also means "it seems" or "apparently" and can replace انگار here without changing the meaning or requiring a different verb tense. However, انگار is much more common in everyday spoken Farsi, while گویا has a slightly more formal or literary tone.
