— Thus, if you discover a spruce and your name is Engelmann, the tree becomes Picea engelmanni, which is only Engelmann’s spruce in Latin; if you discover a nonmetallic element and name it iodine, you have only called it looking like a violet, by giving it a Greek name for the color of its vapor; if you suffer from pneumonoultramicroscopicsilicovolcanokoniosis, you may be fatally ill, but your disease is being described in a series of classical syllables.
