In Shakespeare's The Tempest, a sea-change is a change brought about by sea: Full fathom five thy father lies ... / Nothing of him that doth fade / But doth suffer a sea-change. This meaning is the original one, but it's now archaic. Long after sea change had gained its figurative meaning, however, writers continued to allude to Shakespeare's literal one; Charles Dickens, Henry David Thoreau, and P.G. Wodehouse all used the term as an object of the verb suffer.
: a big and sudden change
