指留在表面上的可见痕迹、斑点或符号，往往是无意造成的、具有物理性质，不一定传达任何信息。

Both can mean a visible symbol. Sign is a symbol meant to send a message, understood by convention; 'a sign of trouble' is not compared. Mark is a visible trace left on a surface, often unintentional; 'a good mark on a test' is not compared.
两者都指能传达信息的可见标记，但 sign 常指有意做出的、约定俗成的示意动作或标志，而 mark 更常指留在物体表面的痕迹或做的记号，不一定带有交流意图。这里不比较 mark 的“分数，标准”等其他义项，也不比较 sign 的“迹象，征兆”等其他义项。
