What does cossack mean?
A Cossack is a member of a group of predominantly East Slavic-speaking peoples who formed semi-autonomous military communities in the steppes of southern Russia and Ukraine from roughly the fifteenth century onward. Renowned for exceptional horsemanship and fierce fighting ability, Cossacks organized themselves into self-governing bands known as hosts, living beyond the reach of neighbouring empires before many entered imperial service as frontier cavalry under the Russian tsars. The name derives from a Turkic word meaning 'free adventurer' or 'freebooter', reflecting their origins as escaped serfs and frontiersmen. In modern English the term appears most often in historical writing about Russia and Eastern Europe, and attributively for distinctive styles of clothing such as the fur-trimmed Cossack hat or loose Cossack coat. The word evokes romantic images of mounted warriors on the open steppe, though it can also carry harsher associations from Cossacks' historical role in suppressing revolts.

Etymology of cossack
The word enters English in the late sixteenth century from Polish 'kozak' and Russian 'kazak', which themselves derive from Turkic 'qazaq', meaning 'free man', 'adventurer', or 'freebooter'. The same Turkic root independently produced the name of the Kazakh people of Central Asia, making the two ethnonyms linguistic cognates despite referring to distinct peoples. The term originally described fugitives and frontiersmen who settled the steppe lands beyond the reach of Polish-Lithuanian and Muscovite authority.

How cossack is actually used
Usually capitalized when referring to the ethnic or historical group ('a Cossack'), but often lowercase when used attributively for clothing styles ('a cossack coat'). The word carries strong historical connotations of martial independence and, in some contexts, of repression, since Cossack units were used by the Russian Empire to suppress uprisings.
Easily confused with cossack
A Kazakh is a member of the Turkic ethnic group native to Kazakhstan; although both words derive from the same Turkic root 'qazaq', they refer to entirely different peoples.
