Brush Up on Your Latin With vade mecum

Vade mecum is Latin for go with me (it derives from the Latin verb vadere, meaning "to go.") In English, "vade mecum" has been used (since at least 1629) of manuals or guidebooks sufficiently compact to be carried in a deep pocket. But from the beginning, it has also been used for such constant companions as gold, medications, and memorized gems of wisdom.
