jajūna
This is the word for the center of a delimited space. So, jawēlre jajūna is the center of a cirle. There is also the word sajūna which refers to one’s soul or one’s personhood. This comes from a different tradition than the more formal word senārre. This word is also the source of the suffix –iūna or –jūn, which commonly appears in names.
+1 for this one! Really cool idea. (Also, I like the picture of a circle from your last post.)
Thanks!
