Etymology
the word 'glaucous' traces its lineage directly to the ancient greek adjective 'glaukos', which originally described a shimmering or gleaming quality, often applied to the pale silvery-green of olive leaves or the grey-blue hue of the sea. this greek term passed into latin as 'glaucus', retaining its association with a pale, greyish-green colour. the english form emerged in the 17th century, adopting the latin stem 'glauc-' and appending the common adjectival suffix '-ous'. the semantic journey thus moved from a general sense of 'gleaming' or 'pale' in greek to the more specific botanical and descriptive meaning in modern english, denoting a dull greyish-green or blue colour, often with a powdery or waxy surface coating.
Analysis
glauc (from latin 'glaucus', from greek 'glaukos', meaning gleaming, greyish, bluish-green); ous (english adjective-forming suffix, from latin '-osus', meaning full of, characterized by).
