Superlative form of 'green'; the most green in color, most environmentally conscious, or most inexperienced and naive.
From green + -est (superlative suffix). The word combines the literal color sense with figurative meanings: environmental consciousness (from the modern 'green' movement) and naivety (from the old sense of 'green' meaning young or inexperienced).
The word 'greenest' brilliantly demonstrates how language captures multiple meanings—the same word can mean most eco-friendly AND most naive, because both come from different historical metaphors for the color green!
