stalwart: [14] The ancestor of stalwart was Old English stǣlwierthe. The second half of this compound adjective denoted ‘worth, worthy’, but the precise significance of the first element is not clear. It represents Old English stǣl ‘place’, perhaps used here in the metaphorical sense ‘stead’, so that etymologically the word would mean ‘able to stand someone in good stead’.

But stǣl itself may have been a contraction of stathol ‘foundation’, so the underlying meaning of the compound could be ‘foundation-worthy’, hence ‘firmly fixed’ (an adjective statholfæst existed in Old English, meaning ‘firm, stable’). South of the border it became stalworth, which had virtually died out by the end of the 17th century. But the Scottish variant stalwart, first recorded in the late 14th century, survived, and was brought into the general language by Sir Walter Scott.
