Does anyone know what 'C change' or 'See / Sea Change' means, please?

Answer 1

The phrase is a quotation from Shakespeare. It comes from Ariel’s wonderfully evocative song in The Tempest:

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.

The Oxford English Dictionary finds the first allusive use in one of Ezra Pound’s poems from 1917. But examples can be found a little earlier than that, as in The Great White Wall by Julian Hawthorne, dated 1877: “Three centuries ago, according to my porter, a sea-change happened here which really deserves to be called strange”.
(quoted from the World Wide Words)

Answer 2

The expression is "sea change" and I've heard it used in 3 different ways: 1) a large change, 2) a fundamental change, 3) an abrupt change. The expression is usually used in reference to the policy or opinion of a large group of people, e.g. scientific opinion, public policy, governmental programmes. In some sense, the above 3 meanings are related, i.e. an abrupt change is apt to be a large one and the outward or observeable effects probably signal a similarly sized change in underpinning or fundamental thought on the matter.
