briefcase

The word 'briefcase' is a transparent 20th-century compound, logically combining two older English words. 'Brief', with its Latin root meaning 'short', evolved through legal terminology to signify a concise written document or set of papers. 'Case', also from Latin, retained its core meaning of a protective container. The compound thus literally denotes a 'document-container', a portable box designed specifically for carrying important papers, reflecting the modern professional's need for organized, mobile document storage.

Structure: brief (document) + case (container) - brief: From Latin brevis (short), via Old French brief (letter, summary). In English, it came to mean a summary of facts or a set of instructions, especially in a legal context. - case: From Latin capsa (box, receptacle), via Old French casse. In English, it denotes a container designed to hold or protect something.
