Etymology: Latin "hostis" originally meant a stranger or foreigner, and only later came to mean an enemy. The same ancient root gave Latin "hospes," meaning a guest or host, so English "host" and "hostile" are distant relatives, a pair that started out close in meaning. The link is traditionally traced to "hostis," though the exact details of that ancient root remain uncertain. "Hostile" comes from the Latin adjective "hostilis," derived from "hostis," and carries the sense of an enemy's attitude. "Hostiler" is simply the comparative form, made by adding "-er" to "hostile," the same way "colder" comes from "cold." Used as a noun for a more hostile attitude, it is a rare coinage rather than a long-established term.
