marks

Marks is a broad term used to describe signs, symbols, or indicators that convey information, identify objects, or denote value. The concept spans language, law, science, education, and everyday life.

In language and typography, marks include punctuation marks such as periods and commas, as well as diacritical or accent marks that modify pronunciation or meaning. Other marks, such as quotation marks or brackets, organize text and indicate structure.

In education, marks refer to assessments of performance, typically expressed as a numeric score or a letter grade. They are used to gauge mastery, progress, and eligibility for advancement, and scales vary by country and institution.

In law and commerce, a mark can be a trademark or service mark—signs, logos, or names legally registered to identify and protect a company’s goods or services. Marks help distinguish brands and prevent confusion in the marketplace.

In science and medicine, markers identify the presence or state of a substance, condition, or trait. Genetic markers point to specific gene variants; biomarkers are measurable indicators used in diagnosis, prognosis, or treatment monitoring.

Other uses include marks on maps or devices that designate locations, bookmarks or markers in software, and birthmarks or scars that document biological traits or history.
