It's a cmavo class. Previously incorrectly glosed as "part of speech". "Part of speech" actually means noun, verb, adjective; which in Lojban are analogous to gismu, tanru, selbri, etc.
selma'o has been being used for lexeme (non-terminal in the formal grammar), so it ends up including non-cmavo: BRIVLA, CMENE. As pointed out by John Cowan, however (http://groups.yahoo.com/group/lojban/message/9513),
- It's certainly bogus to call CMENE a selma'o, though the internal code of the parser does (as well as BRIVLA). In Lojban, a better term such as vlalei would be preferred. Then there are 3 vlalei and 120+ selma'o.
Naming selma'o in Lojban is a perennial problem. To say that .ui belongs to selma'o UI, you can try
- zo .ui cmavo la'e zo .ui
- zo .ui cmavo le .ui zei klesi
- zo .ui cmavo la'o gy UI gy
- zo .ui cmavo la .uik. (cf. jek, gihek, etc.)
- zo .ui cmavo zo .ui (cmavo: x1 is a cmavo whose syntax is the same as that of word x2)
- How about saying that zo .ui cmavo le selcinmo? after all, the se cmavo (hence selma'o) is the function it performs - .ui is an attitudinal. I don't think all "selma'o" really do se cmavo, so we should not try to say in Lojban that xu has the same function as .ui. It does not. Simply, I feel that the x2 of cmavo should be a short version of the function it performs, though I suppose I'd be satisfied with the cmavo the selma'o is named after - zo .ui cmavo zo .ui - mi'e. .kreig.daniyl.
- Nobody is saying that xu has the same function as .ui. Only that they have the same syntax. (syntax != semantics) --Jay
- You can try coming up with new words to describe each of the hundreds of selma'o; but I suggest something that sticks with the current established names is slightly saner. What's the word description of GUhA, in less than ten words? And I think using cmavo xy. referring to Lojban cmavo as anything other than "is of selma'o X" is going to be utterly uncommunicative; what else do people expect you to say of .ui? -- nitcion

Ugh. These are all blyeech. I can't find the thread this was discussed on in the List. -- nitcion
(I vote for something figurative like pevyseljimca.)
selma'o have been subdivided into numbered classes (e.g. UI1, UI2, UI3...), for semantic reasons.
For a list of every selma'o, consult chapter 20 of The Complete Lojban Language.
