slav

The word 'slav' originates from the Medieval Latin term 'sclavus', meaning 'slave'. This Latin term was derived from the ethnic name 'Slavus', referring to the Slavic peoples. During the early Middle Ages, following wars in Central and Eastern Europe, many Slavs were captured and sold into bondage, leading their ethnic name to become synonymous with servitude in Western European languages. This term passed into Old French as 'esclave' and was subsequently borrowed into Middle English, where it lost its initial vowel to become the modern word 'slave', generalizing from its specific ethnic origin to denote any person held in servitude.

The word is a simplex. It entered English as a loanword from Old French 'esclave', which derived from Medieval Latin 'sclavus'. The ultimate origin is the ethnic name 'Slav', as Slavic peoples were commonly enslaved in Central Europe during the early medieval period.
