The word "star" ultimately derives from the Proto-Indo-European root "h₂stḗr" also meaning star, but further analyzable as h₂eh₁s- ("to burn", also the source of the word "ash") + -tēr (agentive suffix). Compare Latin stella, Greek aster, German Stern. Some scholars believe the word is a borrowing from Akkadian " istar " (Venus), however, this is in doubt. "Star" is cognate (shares the same root) with the following words: asterisk, asteroid, astral, constellation, Esther.
