What does -naut mean?

The combining form -naut is used like a suffix indicating a person engaged in the navigation of a vehicle.

Examples of -naut

The first part of the word, astro, is a combining form that means “related to stars, celestial bodies, and outer space.” The form -naut, as we’ve seen, comes from a Greek root that means “sailor.” Astronaut literally—and very poetically— translates to “star sailor.” Less etherally, astronaut can be literally glossed as a “spacecraft navigator.”
