Some co words carry a true prefix, co-, meaning together or jointly, as in cooperate, coexist, and coordinate. Others, like coast, coffee, and comet, simply happen to begin with these letters without carrying that meaning. Comparing the two groups helps learners see which words share a real family connection and which just look alike.
