How did pilgrims say hi?

Answer 1

Considering that the Colonists were from different countries, speaking different languages, they would have spoken in their native language, e.g. the language of their former homeland.

Answer 2

The Pilgrims likely greeted each other with a simple and polite "hello" or "good day". They were English colonists who followed European customs and manners, so their greetings would have been similar to those used in England at the time.
