Clarus from Latin. I especially like the "poet., of the wind" reference.
clarus -a -um [bright , clear, distinct]; poet., of the wind, [making clear, bringing fair weather]. Transf., to the understanding, [clear, evident, plain]; of reputation, [illustrious, distinguished]; in bad sense, [notorious]. Hence adj. clare, [clearly, brightly, distinctly; illustriously].
An aside. Its a testement to the reputation of Frank that its bringing new, and seldom, posters out of the woodwork at the prospect of winning a Van Alstine component. Kudos Frank!
