With the Supreme Court's death penalty decision, we're going to hear more about this country's "evolving standard of decency," so let's have a little vocabulary lesson.
Devolve is not really the antonym of evolve, or at least it wasn't until recently. Devolve means a transer or delegation (of a duty or responsibility, for example) to another. We can say that, because of the county's dissolution of the cumulative bridge fund, maintenance of Fort Wayne's bridges has devolved on the city.
