What is a sea change?

At an in-house writers’ circle Thursday, one colleague brought up “sea change,” a phrase that seems overused these days. We wondered where it came from and what it truly means. I thought of it as a complete turnaround, a 180-degree shift in the course of a ship. But that’s not quite right.

A “sea change” is defined as a profound change or a transformation in the very nature of something. After a “sea change” the thing is fundamentally different.

Evan Morris in “The Word Detective,” along with other sources, says the term comes from Shakespeare’s “The Tempest.”

Shakespeare meant a transformation brought about by the sea. He wrote these lines:

But doth suffer a sea-changeinto something rich and strange.

Besides fundamental change, a sea change also occurs over time. We could say the role of women in the western world has undergone a sea change. The change is profound and it happened over many years. A sea change is not like a wave swelling and crashing on the shore.

The Mavens’ Word of the Day and World Wide Words also explain “sea change.” Professor Paul Brians says to avoid the phrase.
