x1 is a tosmabru word
Note: for obvious reasons, zo will probably not work here. You probably want lo'u/le'u or zoi to quote x1. A tosmabru word looks like a lujvo, but it falls apart into several cmavo and a lujvo/gismu. For more see http://mw.lojban.org/index.php?title=tosmabru_test. See also valslinku'i.
