The state or condition of being extant; the fact of still existing or surviving.
From Latin extans (existing, standing forth), from ex- (out) + stans (standing). This rare noun form describes the quality or state of something still being in existence.
Librarians and historians use 'extant' to mean 'still existing,' and 'extancy' is the noun form—it's how they talk about whether ancient texts have survived to the present day.
