Not knowing about "selratni", I made up "cmuxu'i" for chemical element, and used "jicmu" in the names of a few of them: jicmrboro, cancmu, sackycmu, lurcmu, tedjicmu. Is that a good root word for them? Is there a better? What should we call other kinds of elements, such as the Chinese elements, the four elements of the ancients, or Euclid's Elements? phma
