Sea-change or seachange, according to the Oxford English Dictionary, means "a change wrought by the sea." The term originally appears in William Shakespeare's The Tempest in a song sung by a supernatural spirit, Ariel, to Ferdinand, a prince of Naples, after Ferdinand's father's apparent death by drowning:
Full fathom five thy father lies,
Of his bones are coral made,
Those are pearls that were his eyes,
Nothing of him that doth fade,
But doth suffer a sea-change,
into something rich and strange,
Sea-nymphs hourly ring his knell,
Ding-dong.
The term sea-change is therefore often used to mean a metamorphosis or alteration. For example, a literary character may transform over time into a better person after undergoing various trials or tragedies (e.g. "There is a sea change in Scrooge's personality towards the end of Charles Dickens' A Christmas Carol.") As with the term Potemkin village, sea-change has also been used in business culture. In the United States, sea-change is often used as a corporate buzzword. In this context, it need not refer to a substantial or significant transformation, but can indicate a far less impressive change.
