Having nothing written or printed on it to tell you what it is or whose it is. An unmarked box could hold anything; an unmarked grave has no stone with a name; an unmarked road has no sign to say where it goes; an unmarked police car is an ordinary-looking car with no police badge or colours on it, so you cannot tell what it is until it stops you.

Having nothing written or printed on it上面沒有任何文字或印刷 to tell you what it is or whose it is看不出它是什麼、是誰的. An unmarked box沒有標記的箱子 could hold anything可能裝著任何東西; an unmarked grave沒有標記的墓，has no stone with a name沒有刻名字的墓碑; an unmarked road沒有標記的路，has no sign to say where it goes沒有路標告訴你通往哪裡; an unmarked police car沒有標記的警車 is an ordinary-looking car with no police badge or colours on it是一台外表普通、沒有警徽或警車配色的車, so you cannot tell what it is until it stops you所以在它把你攔下來之前你根本看不出來.

That last one is by far the most common in the news, and it shows the flavour of the word well: the missing label is often the point, either because someone wanted to hide something or because someone was forgotten.

So the word often carries a small shadow of anonymity or neglect所以這個字常常帶著一點匿名或被忽視的陰影 — an unmarked grave is sad無名墓讓人覺得悲傷, an unmarked van is faintly worrying沒有標記的貨車讓人隱約覺得不安.

The word has two other uses your students will meet. In school, unmarked homework is homework the teacher has not yet corrected or given a score to. And of a body or a surface, unmarked means unhurt, with no scratch or stain on it — 'the table was still unmarked after twenty years'.
