Learn Farsi: شاعر درباره‌ی رخان زیبا شعر می‌سراید. - The poet composes poetry about the beautiful faces.

The suffix -ân is historically used for living things, but in formal or literary Farsi, it is also used to pluralize paired body parts (like eyes, lips, and hands). While رخ is often translated as "face", it traditionally refers to the "cheek". Since cheeks are a paired body part, the poetic plural becomes رخان (rokhân).

The verb is می‌سراید. What is the infinitive, and how do we get this present tense form?

The infinitive is سرودن (sorudan), meaning "to compose (poetry)" or "to sing". Its present stem is irregular: سرای (sarây). To form the present tense "he/she composes", we add the prefix می (mi-) and the third-person singular ending -ad, giving us می‌سراید (mi-sarâyad).

Where are the Ezafe connectors used in this sentence?

There is one explicit Ezafe and one hidden Ezafe. The preposition "about" is درباره (darbâre), which takes a written Ezafe -ye (the ی) to connect to its object. There is also a standard, unwritten Ezafe connecting the plural noun رخان (rokhân) to its adjective زیبا (zibâ), making the pronunciation رخانِ زیبا (rokhân-e zibâ).

Why isn't there a plural marker on شعر (she'r) if the translation says "poetry"?
