The word "dextral" comes from the Latin word "dexter", which means "right" or "right hand". In Latin, "dexter" is derived from the Proto-Indo-European root *deks- or *deḱs-, meaning "right" or "to the right". This root has cognates in various Indo-European languages, such as Sanskrit "dakṣiṇa" and Greek "dexios", which also convey the idea of "right" or "skillful". Thus, "dextral" ultimately refers to something pertaining to or favoring the right side or right-handedness.
