The term 'sunyata' is a direct transliteration of the Sanskrit word 'śūnyatā,' which is a noun derived from the adjective 'śūnya,' meaning 'empty' or 'void,' combined with the abstract noun suffix '-tā.' In Buddhist philosophy, particularly within the Mahayana tradition, it evolved from a literal notion of emptiness to denote the profound doctrine that all phenomena are empty of intrinsic, independent essence or self-nature. This concept traveled through Buddhist texts into Western philosophical and spiritual discourse, where it retains its specialized meaning, representing a core metaphysical principle rather than a mere physical absence.

This is a direct loanword from Sanskrit (śūnyatā). It is not segmented into morphemes based on English spelling.
