x1 is a Lojban-derived zi'evla/"self-loan-word" with meaning x2 derived from word(s) x3
From lojbo + fu'ivla, shortening of jbojbofu'ivla. See zi'evla. Examples of jbofuvi: crenzuue, gentufa, aiste, and of course, jbofuvi itself. // Although usually refers to zi'evla, is not necessarily limited to it - jinda (from jipno dirce tarmi) is an experimental gismu that's a jbofuvi, while dzipo (from cadzu cipni) is an original gismu that's also a jbofuvi.
