Learn Farsi: استاد ما یک برابری‌خواه واقعی است.

The suffix -khâh is the present stem of the verb khāstan (to want or seek). When attached to a noun like barābari (equality), it creates a compound word describing someone who seeks or advocates for that concept. Here, it literally translates to equality-seeker.

What is the structure of the base word barābari before the suffix is added?

It is built from the adjective barābar (equal). By adding the noun-forming suffix -i, it becomes the abstract noun barābari (equality). This common word-building pattern creates the foundation for adding the -khâh suffix.

Where exactly is the unseen ezāfe vowel placed in the phrase yek barābari-khāh vāqe'i?
