Er, comma—at least it seems like that"s what we"re seeing. And just like a comma breaks up a sentence, this structure called a breakwater interrupts the Pacific Ocean, punctuating waves with a crash before they can disturb this Bali beach. Whether its resemblance to a comma (or is that an apostrophe?) was intentional or not, it"s a fine visual for today"s syntactical celebration. That"s correct: It"s Grammar Day! (Note to hardline grammarians: We know punctuation—like a comma—isn"t exactly grammar, but we"re loosening the linguistical reins a bit in the generous spirit of Grammar Day. So put that red pen down, smarty-pants.)
