Latin word corona (meaning crown) comes from Ancient Greek κορώνη (koróni - garland, wreath) which probably derives from the Proto-Indo-European root *sker- (turn, bend). The name has been applied to the COVID-19 coronavirus and other viruses in this group allegedly due to the crown-shaped protein spikes around the virus particles when viewed under the microscope.
