This accent would have been influenced by:
* The accents of the British settlers: The dominant influence would have been the accents of the English colonists who settled in the area. This could have included variations of Southern English, Northern English, and even Irish accents.
* Local dialect and regional variations: Specific accents and pronunciations would have developed in different regions of the colonies.
* Native American influences: It's possible that some Native American language features might have influenced colonial speech, particularly in areas with large Native American populations.
Unfortunately, we don't have recordings of Mercy Otis Warren's voice, so we can't know for sure how she spoke. However, her writings provide some insight into her language and vocabulary, which can help us understand the approximate sound of her accent.
It's important to note that "early American colonial accent" is a general term, and there would have been many variations within it.
