One can take a cue from Japanese (keigi) & label these attitudinals as follows:
ga'inaicai reverential
ga'inaisai humble & formal
ga'inairu'e formal
ga'icu'i polite
ga'iru'e plain
ga'isai blunt
ga'icai rude
(Note that iocai can be substituted for ga'inaicai ktp; & this
presumably distinguishes personal from social use of these signifiers. I.e. the ga'i-series is implicit ro'a & the .io-series is implicit ro'anai.)
One suggestion is to use the top level to address cevni, the second kesfange, larcu dacti, & lijda ralju; the third, minde remna; the middle one, remna drata; the fifth, tinbe remna; the sixth, skami, noryru'i, & danlu; & the last one, ti'ocpi, cinki, & spati.
Seems to me that ga'icu'i should be "plain", the midpoint between the two. --xod
Yeah, I agree. (My intent was for this to be the default level for strangers, which in most languages that recognize these distinctions is a tad formal. The next level below it, is familiarity.)
And Michael, you can oracularly suggest all you want, but there's a fair few humans in this world I like to think of in ga'icai terms... (fu'e.iosai mi do tugni fu'o)
