* English: This was the dominant language, brought by English settlers and used in government, commerce, and daily life.
* Dutch: The northern part of New Jersey was originally settled by the Dutch. While English gradually replaced Dutch, some communities continued speaking it for some time.
* Native American Languages: Various Native American tribes inhabited the area, each speaking their own language. These languages were gradually supplanted by English.
* French: Though French influence in New Jersey was less than in other colonies, some French settlers and traders were present.
* German: A small but growing German-speaking population arrived in the 18th century, mostly in the southern part of the state.
So, while English was the primary language, the colonial era of New Jersey saw a mix of languages reflecting its diverse origins.
