They like to know where words come from, how they evolved, and where phrases originated. Toss an unfamiliar word at a corvidophile, and chances are that they will try to figure out its meaning, rather than shrug it off. Many corvidophiles speak more than one language, or know significant amounts of vocabulary in some foreign tongue. They enjoy using their knowledge, too, mixing foreign words in with familiar, or describing concepts in whatever language is best suited to the task. This is especially true when they are around others who speak multiple languages.
Poetry is another passion common to most corvidophiles.
When given the opportunity, they can spout verses or pore over volumes of poetry for hours. Again, this is most common when there are others around to share the activity with. Some corvidophiles take their love of words so far as to insist there are not enough words in the English language. When possible, they will borrow from foreign tongues, or use words from Douglas Adam's book, The Meaning of Liff . It's important not just to get the meaning across, but the correct meaning across.
