Lavalier → The word originates from French 'lavalier', which refers to a type of decorative pendant or ornament worn around the neck. It is derived from 'laval', meaning 'of the valley', which is a reference to the style or design of the ornament. The term signifies a piece of jewelry that hangs down, often resembling something that might be found in a valley.
Think of a decorative piece that hangs down like something found in a valley — that's why a 'lavalier' is a type of ornamental pendant.
