Müsekkin

Arabic The term derives from the Arabic root s-k-n (س ك ن), meaning "to stop, to rest, to attain tranquility." It is formed from the word musakkin (مسكّن), which is constructed in the mufaˁˁil pattern (Type II active participle) from the verb sakana (سَكَنَ), meaning "he became still, he ceased." This verbal pattern imparts causative and continuous qualities to the verb; thus, musakkin denotes not merely a passive state of calm, but an external agent or instrument that alleviates pain, halts disturbance, and restores stability—a "soothing" agent or substance.
