Positive characterization of fu'ivla space

Considering only words that meet these criteria:

  • End in a vowel and have at least one consonant pair in the first five letters, ignoring apostrophes
  • Have no 'y'
  • Have at least two syllables
  • All adjacent letters are valid in brivla, and initial pair, if any, is valid
  • Have no four consonants in a row, none of which is syllabic,

here are some kinds of valid fu'ivla. Please check this for r and n corner cases and any other errors.

  • Any word of the form V(V)CC(C)V. E.g. iglu, uiski.
    • These depend on the "pause between stressed cmavo and brivla" rule for validity and are likely to be misheard.
        • You could also say that they rely on the mandatory pause before all words which begin with vowels, and are not likely to be misheard.
        • Only the stress differentiates, say, .iglu ta from .i gluta.
          • Same thing that differentiates miglu ta from mi gluta, nothing special about iglu here.
        • The example was .iglu zbasu. .IgluZBAsu is .iglu zbasu, whereas .I.gluZBAsu is .i gluzbasu.
          • Same thing happens between MIgluZBAsu which is miglu zbasu, and MI.gluZBAsu, which is mi gluzbasu. Nothing special about iglu here.
  • Any word of the form V(V)CC(C)VV, where the final VV is a diphthong.
  • Any word beginning with a consonant cluster, or with the second syllaboid beginning with a non-initial cluster, and containing
    • VCVCV E.g. krotalu, stramoni.
    • C/CVCV E.g. salmandera, mlongena.
    • CC/C E.g. fasxolarkto. This includes all type 3 fu'ivla.
    • CCCVV E.g. spra'i, spraile
    • CCCC E.g. damskrima.
    • VVV E.g. bru'a'a.
    • VV not valid in lujvo. E.g. srutio.
    • initial V E.g. ernace.
    • final VVCV E.g. kri'ibe, spraile.
    • VVC/C other than in initial CVVC/C
    • VVCCVV other than in initial CVVC/CVV
    • C/C followed by a number of letters multiple of three. E.g. salmandera, mlongena, braklundera.
    • CCC followed by a 2 mod 3 number of letters. E.g. spra'i
    • CVCV followed by a 2 mod 3 number of letters.
    • VV (other than in initial CVV) followed by a 1 mod 3 number of letters.
    • initial CVV followed by a 2 mod 3 number of letters.
    • initial CVC followed by a 1 mod 3 number of letters.
    • initial CCVV followed a 1 mod 3 number of letters.
    • CCC and a vowel in a position that is 2 mod 3 counting after CCC. E.g. spraile, stramoni.
    • any other string that can't appear in a lujvo or lujvo minus initial CV.


All of the following are subsumed in the above.

  • Any word beginning CCC and having a vowel in a position that is 2 mod 3, not counting apostrophes. E.g. spraile, stramoni.
  • Any word of the form CCV(CCV)+CV where one of the CC's (not the first) is replaced with C/C. E.g. mlongena, braklundera.
  • Any word of the form CVC/CVCV, CVC/CVCCVCV, CVC/CVC/CVCV, etc. E.g. salmandera.
  • Any word beginning VC/CV or VVC/CV or VVVC/CV. E.g. ernace.
  • Any word beginning with a consonant cluster, or with the second syllaboid beginning with a non-initial cluster, and ending VCVCV. E.g. krotalu.
    • Can be generalized to: Any word beginning with a consonant cluster, or with the second syllaboid beginning with a non-initial cluster, and containing VCVCV or C/CVCV. E.g. krotalu.
  • Any word beginning with a consonant cluster, or with the second syllaboid beginning with a non-initial cluster, and containing a vowel pair that is not valid in lujvo. If it would be a valid lujvo on changing the vowel pair, this is disputed. E.g. srutio.
  • Any word beginning CVCCCC, where the CCCC includes a non-initial pair, or CCVCCC. This includes the type 3 fu'ivla with full gisms. E.g. damskrima (which is disputed because the 'm' and 'r', though syllabic consonants, are not actually syllabic in this word).
    • The CCVCCC part is wrong. leCCVCCCa is a lujvo form.
  • Any word beginning with a consonant cluster, or with the second syllaboid beginning with a non-initial cluster, and ending in CC/CV or C/C/CV. E.g. fasxolarkto.
    • Can be generalized to: Any word beginning with a consonant cluster, or with the second syllaboid beginning with a non-initial cluster, and containing CC/C or C/C/C. E.g. fasxolarkto.
  • Any word beginning CCVV. E.g. kri'ibe.
    • This needs some restriction. kri'ibei is not valid because lekri'ibei is a lujvo.
      • One possible restriction is "with a number of letters, not counting apostrophes, that is a multiple of three". Any others?
        • kri'ibroda has 9 letters, but lekri'ibroda is a luvjo. It has to be "beginning CCVV and with a number of letters that is 2 mod 3", but then kri'ibe is not an example of this rule.


This is not an exhaustive list.
