This document discusses the origins of words in English and other Indo-European languages. It examines old English words and their modern English descendants to understand Anglo-Saxon culture. It also analyzes cognates across Indo-European languages to reconstruct proto-Indo-European, their hypothesized common ancestral language. Similar basic words across languages suggest inheritance rather than borrowing. Comparing referents represented suggests the original Indo-European homeland was in a northern temperate region near the sea and forests.
