deafness

the word 'deafness' is a straightforward english formation built upon the ancient germanic root for the condition. the core adjective 'deaf' descends from proto-germanic 'daubaz', meaning 'deaf', which itself likely derives from the proto-indo-european root 'dʰewbʰ-', carrying the sense of 'to be obscure, cloudy, or fuzzy'—a semantic shift from obscured perception to a lack of hearing. the suffix '-ness' is a native english morpheme from old english used to form abstract nouns from adjectives. thus, the literal construction 'deaf-ness' logically denotes 'the state or condition of being deaf,' directly linking the physical impairment to the abstract concept of the condition.
