Mark

Common senses

• Sign or symbol — any visible trace such as a mark on paper, a diacritic, or a printed symbol (punctuation marks like the period or question mark).
• Grade or score — a mark given to evaluate performance in education or testing.
• Target or victim — in informal usage, a person who is the object of a scam or attack is called a "mark."
• Unit or currency — historically a unit of account in medieval northern Europe and, in modern times, the Deutsche Mark, Germany's currency before the euro.

These senses overlap: a watermark is both a sign and a guarantee of authenticity; a benchmark is a reference mark for measurement.

Name and religious use

Mark is a common given name and surname in many languages. In Christianity, Saint Mark (the Evangelist) is traditionally credited with one of the four canonical Gospels of the New Testament, called the Gospel of Mark. Saint Mark became an important patron figure in places such as Venice, where his symbol — the winged lion — is widely recognized.

Historical and technical uses

As a historical term, "mark" referred to an amount of weight or monetary value used in medieval accounting across parts of Europe. In modern technical fields, "mark" can mean a flag or tag used to record state (for example, a mark in garbage collection algorithms) or a notation in typesetting and publishing. In sport and other activities it may denote a catch or a designated scoring area.

Because of its many applications, context determines whether "mark" refers to a physical symbol, a level of achievement, a person, or a monetary or technical concept. The word remains common and productive in contemporary English.
