What does bolding mean?
Bolding is the practice of printing or displaying text in a bold typeface so that it stands out from surrounding material. As a noun derived from the verb 'bold' — itself an adaptation of the adjective meaning thick, heavy, or daring — it names both the act of applying this formatting and the visual effect it produces. Bolding is a cornerstone of modern document design: headings, keywords, warnings, and key figures are commonly bolded to guide a reader's eye through a page. Used sparingly, it lends clarity and hierarchy to prose; used excessively, it dilutes emphasis and makes text feel cluttered, which is why most style guides advise restraint. The word belongs mainly to editorial, typographic, and computing contexts, having become widespread only with the rise of word processors in the late twentieth century, when applying rich formatting became something any writer could do instantly. Alongside italics and underlining, bolding remains one of the standard tools for signaling importance in written communication.

Etymology of bolding
Bolding derives from the English adjective 'bold', which comes from Old English 'bald', meaning brave or confident, of Germanic origin and related to Old High German 'bald'. The verb 'to bold' arose in the twentieth century as a back-formation within typesetting and computing, and the gerund 'bolding' followed naturally to name the activity of applying bold type. Its cognates are therefore the other Germanic descendants of that root, such as 'boldness' and 'embolden', though those relate to the older sense of courage rather than to typography.
How bolding is actually used
Bolding is chiefly a technical and editorial term used in discussions of typography, document design, and word processing. It is uncountable and neutral in register, appearing mostly in style guides and design writing rather than everyday conversation.
