What does superscript mean?
Superscript refers to a character, symbol, or number placed above the ordinary writing line. It is used in mathematics to indicate powers and exponents, as in x², and in scientific and technical writing for symbols such as superscript plus and superscript minus. In typography and document formatting, superscript text may be smaller and raised to indicate a footnote, an annotation, or a secondary piece of information. The word can function as a noun, an adjective, and a verb: one may write a superscript, describe a raised character as superscript, or superscript a note in a document. Its position above the baseline provides a compact way to add detail without interrupting the main line of text. The related word subscript refers to the opposite arrangement, with characters placed below the baseline.

Superscript was formed in English from the Latin-derived prefix super-, meaning “over” or “above,” and the Latin scriptus, meaning “written.” The underlying root also appears in manuscript, transcript, prescription, and subscription. The word entered English in the early 17th century, initially referring to a superior or upper character in writing or printing.
