From Lojban
Jump to: navigation, search


Eulojban (la .eulojban. ; standard Lojban name: la .e'ulojban.) is a subdialect of Lojban; specifically, a subdialect of the ce ki tau jei dialect (thus use of Eulojban presupposes use of ce ki tau jei, and is not meant to duplicate anything already reassigned by CKTJ)

It has one characteristic feature: eu is a valid diphthong in Eulojban. This gives 20 more potential monosyllabic cmavo, and potentially also expands rafsi space.

Here are some suggested assignments for this new cmavo space:

  • peu : [NEU] = po'u lo
  • neu : [NEU] = no'u lo (These are like poi/noi but often grammatically more convenient if you only need a single selbri instead of a bridi. poi/noi often need to be closed by ku'o/vau.)
  • veu'u : [NEU] = po'u la (e.g. la .aleksandros. veu'u banli; NEU version of voi'i)
  • geu'u : [GEUhU] - terminator for NEU

Categorical pronoun set

These are pronouns that can be used to refer to any object of that particular category; like natlang pronouns or ra/ru, their referent may be ambiguous. One can always give a more precise description with le [broda], or qualify these pronouns with poi/noi/peu/neu, or for the last word in precision, there's always goi.

  • reu : [KOhA] categorical pronoun: person (prenu); Note: zo prenu cu eutca (eutca defined below); it generally refers to humans, but could refer to anything the speaker considers a "person", e.g. one may use reu to refer to a pet.
  • deu : [KOhA] categorical pronoun: animal, includes humans (danlu)
  • teu : [KOhA] categorical pronoun: inanimate object, includes plants and corpses (dacti jenai ke jmive je danlu)
  • feu : [KOhA] categorical pronoun: female (fetsi)
  • meu : [KOhA] categorical pronoun: male (nakni)
  • zeu : [KOhA] categorical pronoun: place, location (stuzi, mnemonic: zvati / CKTJ-zai)
  • seu : [KOhA] categorical pronoun: abstractions: nu/du'u/ka/etc, and immaterial objects (mucti, mnemonic: su'u)
  • ceu : [KOhA] categorical pronoun: god (cevni)
  • xeu : [KOhA] categorical pronoun: generalized person, "one"/general-you (mnemonic: xanri)
  •  ? : [KOhA] categorical pronoun: text? (maybe do'i which is already in ortho-Lojban)

Still need lervla pronouns, but frustrated by boi?

How's this: In Eulojban, lervla pronouns consist of one and only one BY/BU-group, unless you use this:

  • leu : [LI2] converts number/character-string to pronoun

No more abu za'ure'u cusku problem. Heck, you don't even need boi in abu tavla by cy! Well you'd still need a boi in leu bypyfyky boi za'ure'u cusku, but, you can't win them all. bois will be bois.

A new attitudinal!

  • eu : [UI1] eu = comfort (Aaaah!), eutei = pain/suffering (Ouch!) [exists in JVS as oi'u, but with the scale reversed]

(tei is CKTJ-swapped from ne'e, and is preferred over nai for polar negation in all contexts in Eulojban. In other words, tei is the suffix form of to'e, while nai is the suffix form of na'e.)

And now for something completely different

  • keu : [KE] Temporarily introduces a selskiski-style tanru. E.g. lo keu ckule nixli describes a "school of-type girl" / "girl's school" rather than the other way around. This differs from using co in that place structure still that of the tertau, e.g. in mi keu broda brode do, both mi and do are arguments of broda, while in mi broda co brode do, mi is lo broda, while do is lo se brode.
  • ke'eu : [JOhEU] *highly experimental, even for Eulojban!* Toggles following text to selskiski-style tanru; i.e. all "adjectives/adverbs" come *after* the things they modify, as if you had put keu before every tanru. co still works but only changes place structure, not ordering. ke'eunai switches back to regular tanru style.

More phonemes?

Well crap, we got 20 more monosyllabic cmavo, but already used up 14 of them. (Currently unassigned: beu geu ieu jeu veu ueu) How about...

q might be [ŋ] (cf. Ceqli, Toaq Dzu). This variant might be rendered la .eulojbaq. (standard Lojban: la .e'ulojbang.). This allows even more space (10 more monosyllabic cmavo), such that qa, qai, even qeu are potential cmavo.

q will be considered a distinct phoneme and letter from n. However, n may still be pronounced [ŋ] before k/g/x. As a result, the combinations qk/qg/qx are disallowed.

This would "solve" the problem of how to transliterate certain cmevla, like Bing (Microsoft's search engine); there is disagreement of whether it should be rendered la .bing. or la .bin. . Theoretically, since [ŋ] is supposed to be an allophone of n, the latter would be more correct, but would likely not be pronounced accurately, and might be harder to understand. The former is clearer, but the necessity of pronouncing it with an [ng] / [ŋg] ending is displeasing to some. Under Eulojbaq, it's la .biq.

More phonemic madness: w could be a new vowel, [œ] (stressable), thus la .eulwjbaq. (standard Lojban la .e'ulo'yjbang.) is born (21 more monosyllabic cmavo!). Then wi and wu can be new diphthongs [œi /œj] and [œu / œw], thus la .eulwujbaq. (standard Lojban la .e'uly'ujbang.) is born (another 42 monosyllabic cmavo!).

Suggested cmavo:

  • tw (rafsi -twl-) : [SE] = to'ai
  • vw (rafsi -vwl-) : [SE] = vo'ai
  • xw (rafsi -xwl-) : [SE] = xo'ai

  • gwi : [GOhOI] = go'oi
  • zwi : [GOhOI] = ze'oi
  • bwi : [GOhOI] = bo'ei
  • xwi : [XOhI] = xo'i
  • pwi : [NOIhA] = poi'a
  • nwi : [NOIhA] = noi'a
  • swi : [NOIhA] = soi'a

  • nw  : [KE999] conversion: converts selbri / tanru into nu variant
  • dw  : [KE999] conversion: converts selbri / tanru into du (standard Lojban du'u) variant
  • kw  : [KE999] conversion: converts selbri / tanru into ka variant
  • ni'w  : [KE999] conversion: converts selbri / tanru into ni variant
  • su'w  : [KE999] conversion: converts selbri / tanru into su'u variant
  • si'w  : [KE999] conversion: converts selbri / tanru into si'o variant
  • li'w  : [KE999] conversion: converts selbri / tanru into li'i variant
  • jo'w  : [KE999] conversion: converts selbri / tanru into jo'u (standard Lojban jei) variant
  • mu'w  : [KE999] conversion: converts selbri / tanru into mu'e variant
  • pu'w  : [KE999] conversion: converts selbri / tanru into pu'u variant
  • za'w  : [KE999] conversion: converts selbri / tanru into za'i variant
  • zu'w  : [KE999] conversion: converts selbri / tanru into zu'o variant

(like peu/neu, these reduce the need to close bridi-tails. These are in subselma'o KE999 so as to not conflict with any KE sub-selma'o that anyone else might want to make :p)

  • pw  : [LE] po ("standard" Lojban xu'u) , but in LE (yet more bridi-tail-hate)

Oh, and by the way, the consonant cluster -mz- is unbanned from all Eulojban dialects. You're welcome.

Code switch cmavo

  • cau'eu : [JOhEU] = jo'au tcekitaujau
  • coi'eu : [JOhEU] = jo'au tcekitaujoi
  • cei'eu : [JOhEU] = jo'au tcekitaujei
  • jo'eu : [JOhEU] = jo'au .e'ulojban.
  • qo'eu : [JOhEU] = jo'au .e'ulojbang.
  • qw'eu : [JOhEU] = jo'au .e'ulo'yjbang.
  • qw'wu : [JOhEU] = jo'au .e'uly'ujbang.

  • bi'eu : [JOhEU] Toggles to brivla-cmevla merge. bi'eunai toggles it off.
  • ga'eu : [JOhEU] Toggles to gadganzu usage. ga'eunai toggles it off.
    • Alternatively, lo'w/loi'w could be gadganzu-lo'i/loi'i, and le'w/lei'w could be gadganzu-le'e/lei'e. Gadganzu le'i has less use under the existence of peu/neu.
  • xo'eu : [JOhEU] Toggles xorxes' proposal to disallow letter-strings from having PA. xo'eunai toggles it off. xo'eucei would disallow character strings from having PA *except* within LI...LOhO.
    • Ironically the leu proposal above in Eulojban addresses the same problem as this proposal, thus it isn't actually needed in Eulojban.
  • tau'eu : [JOhEU] Alta parser
  • zau'eu : [JOhEU] Zantufa parser
  • sau'eu : [JOhEU] Spagetufa parser
  • cai'eu : [JOhEU] Camxes parser

  • dai'eu : [JOhEU] Switches to other language. dai'eunai switches back... supposedly... dai'eunai might actually mean something in that other language...
  • xo'e'o'eu : [JOhEU] Elliptical code/dialect/language switch
  • u'u'u'eu : [JOhEU] Switches to U (conlang) [note, there isn't any way to switch back!]

(Yes this set completely breaks the rules of how jo'au works. They're just included here as a completely informal [not to mention somewhat satirical] replacement for the requisite jo'aus)

Bonus cmavo

  • ro'eu : [UI4] emotion category/modifier : related to new dialects. uiro'eu = "Yay! A new dialect!" oiro'eu = "Darn it, a new dialect!" ki'aro'eu = "I didn't understand what you said, cause it's some strange new dialect." euteiro'ero'eu = "My brain hurts from this new dialect."

How about some brivla?

  • dumza (rafsi -deu-) : = stuna, based on du'a
  • nemzu (rafsi -neu-) : = snanu, based on ne'u
  • vumza (rafsi -veu-) : = stici, based on vu'a

  • limseuljau : x1 is the feeling of the sun and water on swimmer x2's chest
  • kangeunre: x1 is the vague, tremulous rose color that x2 sees with their eyes closed
  • sipneurxe : x1 is the sensation of being carried along by a river and also by sleep, felt by x2

Eulojbanistan (euljbogu'e) is an island about twenty kilometers nemzu of Lojbanistan. The Eulojbanistan national animal is the euldipte (crested penguin, gen. Eudyptes, aka mapyzipcpi), and its national flower is the eutkaliptu (eucalyptus, aka maprultricu).
