Westron ribadyan < Adûnaic *irbê–t(h)i/–di anâ ? Assuming that the /r/ is not a changed sound (no begadkefat fricativization in Adûnaic dialects? ;)) and that there was no "milagro" type metathesis, of course. (–i = adjectival ending, SD:435)
(Granted, ri- resembles the Continental Germanic prefixes gi-, ir- and also brings to mind Noldorin ed- in edonna- and might require a slightly less "minimalistic" explanation [e.g. *rîbâd/th- = Arabic mīlād ?]. Regarding the origin of W ..dyan , looking at the etymologies of Old Saxon or closely related infinitives ending in –dian may prove useful.)
Could the Westron word instead contain historical *Ûrî-...i "Sun-sight-ly / Sun-seeing / having seen sunlight"? (... < *b/p-V-C, a biconsonantal verb stem for a basic function "to see", given BITH, NAKH, YAD ?)

Unless the make-up corresponds to English "first-word-ly (person)"... (The element from ʔIR might have to be something a tad longer then — though there is also http://eldamo.org/content/words/word-3789478639.html)
