Strong is the generic term among these, and is the most widely used in figurative applications. By derivation it means having the power of exerting great muscular force. Robust suggests an oaken strength, hence compactness, toughness, soundness of constitution, blooming health, and good size if not largeness of frame. Lusty characterizes the kind of strength that one enjoys possessing, abounding health, strength, vitality, and spirits. Sturdy suggests compactness and solidity even more than robust does; it expresses a well-knit strength that is hard to shake or resist, standing strongly upon its feet. Stalwart suggests tallness or largeness with great strength or sturdiness. Stout is little different from strong; it sometimes means strong to do or to support burdens: as, a stout defender; a stout porter carrying a heavy trunk.
