Etymology
the word 'unsayable' is a modern english formation built from native germanic and borrowed latinate elements. its core, 'say', originates from old english 'secgan', meaning to utter or tell, which itself derives from proto-germanic sagjaną. the negating prefix 'un-', from old english, is one of the most common and productive means of forming opposites in english. the suffix '-able', entering english via old french from latin '-abilis', denotes capability or susceptibility. thus, the literal construction 'not capable of being said' logically yields the modern sense describing things that defy verbal expression due to their extreme, taboo, or ineffable nature.
Analysis
un- (old english, a prefix expressing negation); say (old english, a verb meaning to speak, tell); -able (latin via old french, a suffix forming adjectives meaning 'capable of, fit for').
