Etymology
The word 'whetstone' is a transparent compound from Old English, directly combining 'hwettan' (to sharpen) and 'stān' (stone). The verb 'whet' itself originates from a Proto-Germanic root meaning 'to stimulate' or 'to make sharp', which is also related to the Old English adjective 'hwæt' meaning 'bold' or 'quick', linking the idea of sharpness to mental keenness. The compound simply and logically denotes the object (a stone) used to perform the action (sharpening). Over time, while the separate word 'whet' has become less common in everyday speech, its meaning remains perfectly preserved and clear within this enduring compound noun for a sharpening tool.
