Why this word is great
SEAWRACK — [Noun] A cast-up accumulation of seaweed, especially coarse brown Fucaceae, decomposing along the tide line. From the English words sea (the expanse of salt water) and wrack (seaweed cast ashore, wreckage, or ruin). Unlike "kelp," which denotes the living, anchored forests of order Laminariales, or "driftwood," which speaks of terrestrial origins become flotsam, seawrack is the sea’s own discarded viscera, a terminal deposit. It is the tangled, iodine-scented fringe of the ocean's leavings: a wet mat of bladderwrack popping underfoot, the leathery straps of knot-wrack bleached bone-pale by sun, and the foamy, collapsing brew of detritus at the high-tide mark—the ocean’s quiet, daily rehearsal for its own eventual return to land.
