The Ottoman empire is not the source of the English word slave.
The Ottoman empire was founded at the end of the
13th century and conquered the Byzantine empire in 1453.
The Slav people mitigated into the Balklands from the
6th century, the Greek Byzantine empire engaged in many wars with the Slavs. The Byzantines borrowed and adapted the Slavs' own name as sklavos (σκλάβος). It became the Greek name for the Slavs, and due to large numbers taken captive an alternative word for "slave" doulos (δούλος). The word was adopted in to Latin in the
10th century. Medieval Latin modified it to sclavus and used it in the two senses that developed in Byzantium, "Slav" and "slave." In turn, became the source of the Modern English word slave.
