These verbs all mean to speak with pride, often excessive pride, about oneself or something related to oneself. Boast is the most general: "We confide [that is, have confidence] in our strength, without boasting of it; we respect that of others, without fearing it" (Thomas Jefferson). Brag implies exaggerated claims and often an air of insolent superiority: He bragged about his grades. Crow stresses exultation and often loud rejoicing: No candidate should crow until the votes have been counted. Vaunt suggests ostentatiousness and lofty extravagance of expression: "He did not vaunt of his new dignity, but I understood he was highly pleased with it" (James Boswell).
Some have objected to the use of boast as a transitive verb meaning "to possess or own (a desirable feature)," as in This network boasts an audience with a greater concentration of professionals and managers than any other broadcast vehicle. This usage is by now well established, however, and is acceptable to 62 percent of the Usage Panel.
