rIS joins the set of (related?) verbs beginning with rI- : rIt summon, rI' hail, and possibly rIH energize. See the ja- set: jatlh say/speak, ja' report/tell, jaw chat, jach scream/cry out, jang answer/reply, and jat speak incoherently/mumble (slang; cf. jat tongue). --Voragh From: Felix Malmenbeck == rIS == (verb) appears to have something to do with sending out a signal, or showing up on sensors. Lieven has written on Twitter that this word is similar to {tlhuD}. It used to be used to transmit audio, but now is apparently also a way to transmit life signs: https://twitter.com/Klingonteacher/status/912699349754400770 Quote from Ep.2 ("Battle at the Binary Stars"): CONNOR: "Captain, incoming! Warp signatures detected!" {HoD, paw vay'. rIS 'op pIvghor 'e' vItu'.} In Ep.6 "Lethe", {rISwI'} is used for "transponder".
