the word 'wrath' originates from the old english 'wræþþu', meaning 'fury' or 'anger'. this old english term is derived from the proto-germanic 'wraiþiþō', a noun formed from the adjective 'wraiþaz', which meant 'angry' or 'hostile'. the semantic core has remained remarkably stable, with the modern sense of 'fierce anger' directly inheriting the intense emotional force of its ancient root. the word's journey reflects a common pattern where a descriptive adjective in proto-germanic gives rise to a noun denoting the associated state or quality in its descendant languages.

this is a simplex word of old english origin. it is not productively formed from smaller, independent morphemes in modern english.
