- William H. Gass on the Many Kinds of Commas
"Alas, there are so many kinds of commas: those that lie like rocks in the path of a sentence, slowing its gait and requiring the reader's heed to avoid a stumble; their gentler cousins, impairing a pell-mell flow of meaning the way pebbles slow a stream; commas that indicate a pause for thinking things over; commas enclosing phrases the way the small pockets in a purse hug hairpins or collect bits of loose change; commas that return us to our last stop, and those that some schoolmarm has insisted should be placed, like a traffic cop, between 'stop' and 'and.'"
