YĒCMELĀHUAC truly, certainly, clearly / cierto, verdadero, claramente, seguramente (Z) [(2)Zp.230]. Z characteristically lacks the final –C, as it does in several other similar items. Z also has four attestations of YĒCMELĀN with the same sense (p.28,114,128,230) with –N replacing –HUAC See YĒC-TLI, MELĀHUAC.
