Meaning of CAPTAIN in English
Led captain; an humble dependant in a great family, who for a precarious subsistence, and distant hopes of preferment, suffers every kind of indignity, and is the butt of every species of joke or ill-humour. The small provision made for officers of the army and navy in time of peace, obliges many in both services to occupy this wretched station. The idea of the appellation is taken from a led horse, many of which for magnificence appear in the retinues of great personages on solemn occasions, such as processions, &c.
