The action of making something bold; either strengthening boldness in a person or making text appear in bold typeface.
From 'bold' (verb) plus the present participle suffix '-ing,' which can function as either a gerund (noun) or a continuous verb form. The verb 'bold' itself comes from the Old English 'bald.'
While 'bolding' text is common modern usage, calling the act of strengthening someone's courage 'bolding' is much rarer—it shows how the same word can have both emotional and technical meanings!
