History: BPFK Section: Ban on consonant-glide-vowel strings

Source of version: 13 (current)

!!Problem discussed
The ((The Complete Lojban Language|CLL)) includes a paragraph on diphthongs:
^The first four diphthongs above (â€œaiâ€, â€œeiâ€, â€œoiâ€, and â€œauâ€, the ones with off-glides) are freely used in most types of Lojban words; the ten following ones [[â€œiaâ€, â€œieâ€, â€œiiâ€, â€œioâ€, â€œiuâ€, â€œuaâ€, â€œueâ€, â€œuiâ€, â€œuoâ€, â€œuuâ€] are used only as stand-alone words and in Lojbanized names and borrowings; and the last two (â€œiyâ€ and â€œuyâ€) are used only in Lojbanized names.
[[CLL Chapter 3, Section 4.]^
It is unclear if the paragraph defines a rule for possible diphthongs, or describes diphthongs of existing words. ((jbofi'e)) was designed so that it is applied as a rule to the lexical analysis: ((vlatai)) of it disallows cmavo to include a consonant-glide-vowel (CgV) string. On the other hand, ((camxes)) allows cmavo to include it:
^{CODE()}
cmavo-form <- !h !cluster onset (nucleus h)* (!stressed nucleus / nucleus !cluster) / y+ / digit
{CODE}
[[...]
{CODE()}
onset <-  h / consonant? glide / initial
{CODE}

The BPFK members [https://groups.google.com/d/topic/bpfk-list/OH-sdfvlXsY/discussion|discussed the matter], and put it to [https://docs.google.com/forms/d/1kJLBvjkoDpmvA9vJS_lf8SpCYAZvY4bMx1pj8uhWqRs/viewanalytics|the approval voting].

!!Conclusion
The BPFK disallows CgV in cmevla/fu'ivla/ma'ovla.
It is a stronger restriction than that of CLL, which allows CgV at least in cmevla and fu'ivla. We need therefore to take measures to rescue the existing words that become invalid under the new rule.

!!Measures to rescue the existing words
CgV words on la [jbovlaste.lojban.org|jbovlaste] will be moved into obsolete words category. In order to rescue the words, the following measures can be taken:
#add an apostrophe between Cg and V, and then "CgV" will be separated into two syllables "CV,V"; ex.) kuarka -> ku'arka;
**Attention 1: if the method transforms the word into (pseudo-)lujvo ("fiakre", "fiesta", "kuardicka'u", "tiatro"), it cannot be applied; 
**Attention 2: if the method transforms the word into a bad fu'ivla that fails in ((slinku'i)) ("[http://jbovlaste.lojban.org/dict/ckankua|ckankua]": it is currently (2015-01-04) downvoted, but can revive someday), it cannot be applied;
#or make the glide letter double, and then "CgV" will be separated into two syllables "CV,gV"; ex.) ckankua -> ckankuua; 
**Attention: for fu'ivla beginning with CgV and/or (C)V(g)CCgV..., this method cannot be applied because camxes will regard the result as two words; ex.) fiakre -> fi + iakre; madjio -> ma + djiio;
# if neither 1 nor 2 can be applied, 
## turn it back into type-3 fu'ivla; ex.) fiakre -> marcrfi'akre/marcrfiiakre;
## create a corresponding lujvo; ex.) kuardicka'u -> ratslepaudicka'u;
## turn it back into a zi'evla using a hyphen "n"; ex.) kuardicka'u -> ku'andicka'u;
## reformulate it into zei-lujvo; ex.) kuardicka'u -> ku'arka zei dicka'u;
## create another fu'ivla; ex.) kuardicka'u -> ku'arkadicka'u.
