Over Yonder…

A lot of my family is from Kentucky and I grew up hearing the word “yonder”. I’m not totally sure what that word means. I’ve heard “up yonder, over yonder (left or right) and down yonder.” I’ve heard “get in yonder” and even “Yonder Ho!” Anyway, if you have any insight into this word and it’s origin I would be curious to hear it but for now just know that I am writing  over yonder this week.
