What Greek word, translating to 'universe' or 'order', is used in the etymology of 'cosmonaut'?

Answer

Kósmos

The term cosmonaut is constructed using the Greek word kósmos (κόσμος), which carries the meaning of 'universe' or 'order', combined with the root nautēs (ναύτης), meaning 'sailor'. This linguistic construction yields the definition of a 'universe sailor'. This title was officially established and utilized by the Soviet Union for its space travelers during the competitive era of space exploration. The difference in this initial Greek root—'star' for astronaut versus 'universe' for cosmonaut—highlights the distinct national branding employed by the US and USSR.
