ballein
is also an ancestor of the words “parable” (from “paraballein,” “to compare”), “metabolism” (from “metaballein,” “to change”), and “problem” (from “proballein,” “to throw forward”). Another (somewhat surprising) “ballein” descendant is “devil,” which comes from Greek diabolos, literally meaning “slanderer.”
