The museum has several extant manuscripts from the medieval period.
Extant → It is formed from the Latin root "exstare" (meaning to stand out or to be present) with the prefix "ex-" (meaning out) and the root "stare" (meaning to stand). The word "extant" refers to something that is still in existence or standing out in the present.
Think of something that is 'standing out' ('exstare') and still 'present' — that's what extant means.
