From the Arabic root ف-ر-ح (f-r-ḥ), conveying the idea of joy and elation. The root is Semitic in origin and appears across related languages; the verb فَرِحَ (fariḥa) means "to be happy," and فَرَح is its verbal noun (maṣdar). The root is also found in Hebrew (שִׂמְחָה shares the same semantic field, while פָּרַח means "to bloom/flourish"), pointing to a deep Semitic association between joy and blossoming.

فَرَح is one of the most culturally loaded words in Arabic. In many Arab countries, the word فَرَح (or أَفْرَاح in plural) is the everyday colloquial word for a wedding celebration — so "رُحْنَا عَلَى الفَرَح" means "We went to the wedding." Context usually makes the meaning clear. The word also appears frequently in names (e.g., فَرَح as a female given name) and in classical poetry, where joy is often paired with longing or transience.
