When something is extant, it is still here — not lost, not destroyed, not died out — even though it is very old, or even though many things like it have already gone. We use it most about old books, buildings, laws, and kinds of plants or animals that have managed to last.

When something is extant當一個東西是 extant（現存的）的時候，it它 is still here就是還在——not lost, not destroyed, not died out沒有遺失、沒有毀壞、也沒有絕跡——even though it is very old即使它非常古老，or even though many things like it have already gone或即使很多同類的東西都已經消失了。We我們 use it most about old books, buildings, laws, and kinds of plants or animals that have managed to last最常用它來形容還留存下來的古書、建築、法律，或動植物的種類。

An extant manuscript is one we can still read; an extant species is one that has not died out.

An extant manuscript一份現存的手稿 is one we can still read就是我們還能讀到的那份；an extant species一個現存的物種 is one that has not died out就是還沒有絕種的那種。

Scholars, lawyers, and careful writers like this word. Everyday talk more often says still around or still with us.

Scholars, lawyers, and careful writers學者、律師，和講究用字的作者 like this word喜歡用這個字。Everyday talk日常口語 more often says still around or still with us比較常說 still around 或 still with us（還在的意思）。

Though actually, extant is not a fancy way to say existing. A living cat exists, but we would not call it extant unless we were setting it against cats that have vanished. The word points at survival from the past, not at being alive in a general way.

Though actually不過其實，extant extant 這個字 is not a fancy way to say existing不是「存在」的高級講法。A living cat一隻活著的貓 exists是存在沒錯，but我們 would not call it extant但不會叫牠 extant，unless we were setting it against cats that have vanished除非我們是拿牠跟已經消失的貓做對比。The word這個字 points at survival from the past指的是從過去存活下來，not at being alive in a general way而不是泛泛地說「活著」。
