Where did the saying plenty of fish in sea come from?

The phrase "Plenty of fish in the sea" is thought to have originated in the 16th century. It was first recorded in English in 1546 in a book by John Heywood called "A Dialogue conteinyng the nomber in effect of all the prouerbes in the Englishe tongue."

The proverb is often used to advise someone who is feeling discouraged after a romantic breakup or disappointment. It means that there are plenty of other potential romantic partners out there and that the person should not be too upset over the loss of one person.

The phrase has also been used in a more general sense to mean that there are always new opportunities available and that one should not be discouraged by setbacks.

Some people believe that the phrase originated from the fact that fish are abundant in the sea. Others believe that it originated from the idea that there are plenty of other people in the world who could potentially be a good romantic match for someone who is looking for love.
