Tycho is the Latinized form of Danish Tyge, itself the Danish form of Tóki which comes from Old Norse element Þórr meaning “thunder” which comes from Proto-Germanic *Þunraz (thunder) which derives from a PIE root word. I’ve also seen it listed as possibly being a Latinized form of Greek Tychon meaning “to hit a target; hitting the mark” deriving from PIE root word *dʰewgʰ- (to produce; to be strong, have force). In Greek mythology, Tychon is the name of a daemon of fertility; there’s also another Tychon who is the daemon of chance or accident, who is similar to Tyche, a Greek goddess of fortune,  chance, providence, and fate (even their names come from the same root word).

Origin: Proto-Indo-European
