Today's word is symbiosis. Also pronounced symbiosis and spelled sym B I O S I s. Symbiosis is a noun. It's a formal word that refers to a relationship between two people or groups that work with and depend on each other. In biology, symbiosis refers to the relationship between two different kinds of living things that live together and depend on each other. Here's the word used in a sentence from variety in the old days, which weren't that long ago, there was that ritual moment when a rock and roll idol, in the midst of delivering a classic anthem, would point the mic away from himself and into the arena, indicating that it was time for the audience to take over and sing the lines. It might be Springsteen doing Thunder Road or Madonna doing Holiday. The loving symbiosis of pop star and pop audience doesn't get much more reverent than that. Symbiosis was adopted by the scientific community in the late 1800s, coming ultimately via German from the Greek word symbiosis, meaning living together or companionship. Of course, there are a lot of ways to live together, and accordingly, several flavors of symbiosis. When a biological symbiosis between two organisms is mutually beneficial, it's termed mutualism. For example, ox peckers are birds so named because they peck ticks off of infested cattle and wild mammals, a likely satisfying arrangement for both parties and textbook mutualism when one organism lives off another at the other's expense. However, as for one icky instance head lice do. It's called parasitism. If only parents of elementary school students could call upon an equivalent of oxpeckers to engage in mutualistic symbiosis when the need arose. But alas, with your word of the day, I'm Peter Sokolowski.
