Why this word is great
MORFA — [Noun] A low wetland periodically flooded by salt water; a salt marsh. Borrowed from Welsh morfa ("salt marsh, sea brink"). Unlike "bog" (a freshwater peatland of stagnant quiet) or "estuary" (a river’s broad, mingling mouth), a morfa is the sea’s tentative claim on land, a liminal space of brine and sedge. It is the silvered glint of tidal channels at dusk, the sour tang of samphire crushed underfoot, the way the ground yields like a sigh beneath each step—a landscape that exists only in the quiet negotiation between drowning and drying, neither wholly earth nor water.
