This page is imported from version 83 of the page BPFK Section: Logical Connectives from the lojban Tiki.

Proposed Tags

These are words that might be used pedagogically to mark these word types per [1].

  • (sumti/bridi-tail/general) afterthought logical connective, which we're just calling ALC
    • We might want to come up with something better than "bridi-tail" there.
    • needs a Lojban equivalent?
    • some piece of documentation needs to specify what "general ALC" actually can connect
  • (tanru/general) forethought logical connective (FLC)
    • some piece of documentation needs to specify what "general FLC" actually can connect
    • needs a Lojban equivalent?

Notes

  • Should we do ijeks as well as jeks? That would simplify the jek definitions, but should we bother?
  • Unlimited forethought connection would be really nice. This would need a new cmavo something like {bei}, for all but the last connection. So {ge ko'a gi ko'e} is unchanged, but {ge ko'a gi'oi ko'e gi ko'i} means the same as {ko'a .e ko'e .e ko'i}. {gi} marks "this is the last branch of the next-outer-most FLC".
    • < ksion> Plus probably a terminator in case you forgot saying {gi} before the last argument. < ksion> (That's mostly for speech convienience though).
  • Since all LC are theoretically syntactic sugar for {.i JA}, how to GOhA interact with them?
    • Example: {ko'a brode gi'e broda} -- what's {go'i} after that? {ko'a broda}? Or {ko'a brode gi'e broda} whatever that means as single bridi.
  • Also {vo'A}. What does {ko'a broda ko'e gi'e brode ko'i vo'e} mean? Does {vo'e} refer to {ko'e} or {ko'i}?
    • In most cases it probably should be "refers to the bridi it itself is embedded in".
  • What is the meaning of SE + logical connective, when the SE is something other than {se}?
  • There are gismu equivalents of A and E, but not O and U. This seems unfortunate. Does {nibli} count as an equiv of O?
    • We've apparently known this for a while; see [2]
  • Speaking of which, what do {kanxe} and {vlina} actually mean? Is {le kanxe be ko'a bei ko'e cu broda} semantically equivalent to {ko'a .e ko'e cu broda}? If not, what *is* it semantically equivalent to?
    • Yet another use/mention problem in the gismu. How many does that make?
    • ksion in #lojban suggests: {la'e lu ko'a broda .ije ko'a brode li'u cu kanxe lo du'u ko'a broda kei lo du'u ko'a brode}, which is horrible; I (camgusmis) would rather redefine than be stuck with shit like that.
    • {i lo du'u ge broda gi brode cu kanxe lo du'u broda kei lo du'u brode} from dbrock; same thing
  • xorxes had a proposal that replaces all the logical connectives with JA, which is rather impressive. See [3]
    • selpa'i has a similar proposal which doesn't overload {gi}: [4]
  • All of the definitions need Lindar's touch - I mean, they need expanding into something more, um, conversational English. - .aionys., at prompting from arj.
  • Order of operations for multiple sumti connectives in a bridi needs to be resolved. Is {ko'a .a ko'e broda fo'a .e fo'e} the same as {ko'a broda fo'a .e fo'e .i ja ko'e broda fo'a .e fo'e} (LtR) or is it {ko'a .a ko'e broda fo'a .i je ko'a .a ko'e broda fo'e} (RtL, which would be unusual, or if "and" takes precedence over "or", as in many formal systems)?
    • Here ([5]) is a page about logical connective expansions, which has a section about sumti connections. According to the jbocre to whom I asked, the LtR expansion is the correct one (see the linked page).

Impact

The current definitions are expected to have no particular impact; they should just clarify the current state.

Proposed Keywords

None; there's nothing like this in English except maybe comma. Someone suggested:

Neither an elephant nor a mouse is pink.
ganai mi gunka lo valsi gi mi zmanei la rubis.

General Notes

  • We need a way to easily say "would you like cream or sugar or a donut?" using ji or similar. I *think* this is straightforward, but this is a note to think about it.

There was a recent discussion of this that had people present their different solutions. There are two types: the one with {ji} and the ones with choice from a set.
do djica A ji B ji C ... The helpful answers can all be covered with "(na).e(nai) .e(nai) ..."

A B zo'u do djica ma
do djica ma poi cmima A ce B ce C ce ...
do djica ma poi me A .a B .a C .a ...
The answers "A", "B", "C", ..., "A joi B", ... "noda", "roda". And if you want to be less than helpful: "pada", "su'oda", "me'ida", and so on.

  • How do you reply to {do djica lo ladru ji nai lo sakta} if you want both? Again, might be obvious/well understood, but could use checking.

According to xorxes and mark shoulson (in the thread linked above) the answer is .eja'ai, using {ja'ai} aka the cmavo affirmer.

  • what does {mi djica lo ladru .e nai lo sakta na .e lo titnanba} mean (double negative)?
