highly-skilled

The compound adjective 'highly-skilled' is a transparent modern English formation. Its first element, 'highly', derives from the Old English concept of physical height or elevation, which evolved metaphorically to signify degree, intensity, or superiority. The second element, 'skilled', originates from the Old Norse word for discernment or knowledge, which entered English and came to denote practical ability or expertise. The compound logically combines these notions, describing someone whose level of practical ability or expertise is elevated to a superior degree, emphasizing both the quality and the extent of their proficiency.
