talisman

From French talisman, partly from Arabic طِلَّسْم (ṭillasm, “payment”), from Ancient Greek τέλεσμα (télesma, “payment”); and partly directly from Medieval Greek τέλεσμα (télesma, “talisman, religious rite, completion”), from τελέω (teléō, “to perform religious rites, to complete”), from τέλος (télos, “end, fulfillment, accomplishment, consummation, completion”). Doublet of telesm.

Uncertain. Perhaps a corruption of some Arabic word.
