Is it true that In 1611 the word conversation meant manner of living?

Yes, that's correct! In the early 17th century, the word "conversation" had a broader meaning than it does today.

In the King James Bible (1611), for example, "conversation" often refers to a person's overall conduct and way of life. Here are a few examples:

* "Let your conversation be without covetousness" (Hebrews 13:5). This means "let your way of life be free from greed."

* "Whose conversation is in heaven" (Philippians 3:20). This means "whose way of life is focused on things heavenly."

This broader sense of "conversation" still exists in some contexts today, particularly in religious language. However, the more common meaning of "conversation" now focuses on verbal communication.
