Note: An etymon limited to three western Indo-European branches. Further analysis of the word has been made on the basis of early use of Latin hostis, taken to mean, on the basis of the Law of the Twelve Tables, "outsider due the same right of ownership as a Roman citizen"; from the same base would be hostus "yield of olive oil from a single pressing" (narrowed from a presumed more general "yield, compensation"), the derived verb hostīre "to recompense, requite," and the noun hostia "sacrificial animal, sacrifice" ("recompense to the gods," perhaps originally feminine of an adjective *hostius, the deleted noun having designated an animal; see host entry 5). Ancestral *ghos-ti- could hypothetically be a derivative of an Indo-European verbal base *ǵhes- "take, give in exchange." With the loss in later Roman practice of the strict legal meaning, Latin hostis became restricted in meaning to "hostile outsider, enemy." This shift is noted by varro, who remarked that hostis was used by "our ancestors" in a sense now covered by peregrīnus (see pilgrim).
