sea change
noun
Sea change refers to a big and sudden change or transformation.
Today the term is used for a distinctive change or transformation. Long after sea change gained this 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, but now a sea change is just as likely to be undergone or experienced.
