4.7. fu'ivla and zi'evla

The use of tanru or lujvo is not always appropriate for very concrete or specific terms (e.g. brie or cobra), or for jargon words specialized to a narrow field (e.g. quark, integral, or iambic pentameter). These words are in effect names for concepts, and the names were invented by speakers of another language. The vast majority of words referring to plants, animals, foods, and scientific terminology cannot be easily expressed as tanru. They thus must be borrowed (actually copied) into Lojban from the original language.

There are four stages of borrowing in Lojban, as words become more and more modified (but shorter and easier to use). Stage 1 is the use of a foreign name quoted with the cmavo la'o (explained in full in Section 4.1):

Example 4.44. 

me la'o ly. spaghetti .ly.


is a predicate with the place structure x1 is a quantity of spaghetti.

Stage 2 involves changing the foreign name to a Lojbanized name, as explained in Section 4.1:

Example 4.45. 

me la .spagetis.


One of these expedients is often quite sufficient when you need a word quickly in conversation. (This can make it easier to get by when you do not yet have full command of the Lojban vocabulary, provided you are talking to someone who will recognize the borrowing.)

Where a little more universality is desired, the word to be borrowed must be Lojbanized into brivla form. A rafsi is often attached to the beginning of the Lojbanized form, using a hyphen to ensure that the resulting word doesn't fall apart.

The rafsi categorizes or limits the meaning of the fu'ivla; otherwise a word having several different jargon meanings in other languages would require the word-inventor to choose which meaning should be assigned to the word, since brivla are not permitted to have more than one definition.

Finally, Stage 4 fu'ivla do not have any rafsi classifier, and are used where a fu'ivla has become so common or so important that it must be made as short as possible. (See Section 4.1 for a proposal concerning Stage 4 fu'ivla.)

The form of a fu'ivla reliably distinguishes it from both the gismu and the cmavo. Like cultural gismu, fu'ivla are generally based on a word from a single non-Lojban language. The word is borrowed (actually copied, hence the Lojban tanru fukpi valsi) from the other language and Lojbanized – the phonemes are converted to their closest Lojban equivalent and modifications are made as necessary to make the word a legitimate Lojban fu'ivla-form word. All fu'ivla:

  1. must contain a consonant cluster in the first five letters of the word; if this consonant cluster is at the beginning, it must either be a permissible initial consonant pair, or a longer cluster such that each pair of adjacent consonants in the cluster is a permissible initial consonant pair: spraile is acceptable, but not ktraile or trkaile;

  2. must end in a vowel;

  3. must not be gismu or lujvo, or any combination of cmavo, gismu, and lujvo; furthermore, a fu'ivla with a CV cmavo joined to the front of it must not have the form of a lujvo (the so-called slinku'i test, not discussed further in this book);

  4. cannot contain y, although they may contain syllabic pronunciations of Lojban consonants;

  5. like other brivla, are stressed on the penultimate syllable.

Note that consonant triples or larger clusters that are not at the beginning of a fu'ivla can be quite flexible, as long as all consonant pairs are permissible. There is no need to restrict fu'ivla clusters to permissible initial pairs except at the beginning.

This is a fairly liberal definition and allows quite a lot of possibilities within fu'ivla space. Stage 3 fu'ivla can be made easily on the fly, as lujvo can, because the procedure for forming them always guarantees a word that cannot violate any of the rules. Stage 4 fu'ivla require running tests that are not simple to characterize or perform, and should be made only after deliberation and by someone knowledgeable about all the considerations that apply.

Here is a simple and reliable procedure for making a non-Lojban word into a valid Stage 3 fu'ivla:

  1. Eliminate all double consonants and silent letters.

  2. Convert all sounds to their closest Lojban equivalents. Lojban y, however, may not be used in any fu'ivla.

  3. If the last letter is not a vowel, modify the ending so that the word ends in a vowel, either by removing a final consonant or by adding a suggestively chosen final vowel.

  4. If the first letter is not a consonant, modify the beginning so that the word begins with a consonant, either by removing an initial vowel or adding a suggestively chosen initial consonant.

  5. Prefix the result of steps 1-4 with a 4-letter rafsi that categorizes the fu'ivla into a topic area. It is only safe to use a single 4-letter or CVC-form rafsi; other rafsi sometimes produce invalid fu'ivla. Hyphenate the rafsi to the rest of the fu'ivla with an r-hyphen; if that would produce a double r, use an n-hyphen instead; if the rafsi ends in r and the rest of the fu'ivla begins with n (or vice versa), or if the rafsi ends in "r" and the rest of the fu'ivla begins with "tc", "ts", "dj", or "dz" (using "n" would result in a phonotactically impermissible cluster), use an l-hyphen. (This is the only use of l-hyphen in Lojban.)

  6. Remember that the stress necessarily appears on the penultimate (next-to-the-last) syllable.

In this section, the hyphen syllable is set off with commas in the examples, but these commas are not required in writing.

Here are a few examples:

Example 4.46. 

spaghetti (from English or Italian)

spageti (Lojbanize)

cidj,r,spageti (prefix long rafsi)

dja,r,spageti (prefix short rafsi)


where cidj- is the 4-letter rafsi for cidja, the Lojban gismu for food, thus categorizing cidjrspageti as a kind of food. The form with the short rafsi happens to work, but such good fortune cannot be relied on: in any event, it means the same thing.

Example 4.47. 

Acer (the scientific name of maple trees)

acer (Lojbanize)

xaceru (add initial consonant and final vowel)

tric,r,xaceru (prefix rafsi)

ric,r,xaceru (prefix short rafsi)


where tric- and ric- are rafsi for tricu, the gismu for tree. Note that by the same principles, maple sugar could get the fu'ivla saktrxaceru, or could be represented by the tanru tricrxaceru sakta. Technically, ricrxaceru and tricrxaceru are distinct fu'ivla, but they would surely be given the same meanings if both happened to be in use.

Example 4.48. 

brie (from French)

bri (Lojbanize)

cir,lr,bri (prefix rafsi)


where cirl- represents cirla (cheese).

Example 4.49. 

cobra

kobra (Lojbanize)

sin,cr,kobra (prefix rafsi)


where sinc- represents since (snake).

Example 4.50. 

quark

ku'ark (Lojbanize)

ku'arka (add final vowel)

sas,kr,ku'arka (prefix rafsi)


where sask- represents saske (science). Note the extra vowel a added to the end of the word.

Example 4.51. 

자모 (from Korean)

djamo (Lojbanize)

ler,fr,djamo (prefix rafsi)

le,rl,djamo (prefix rafsi)


where ler- represents lerfu (letter). Note the l-hyphen in "lerldjamo", since "lerndjamo" contains the forbidden cluster "ndj".

The use of the prefix helps distinguish among the many possible meanings of the borrowed word, depending on the field. As it happens, spageti and ku'arka are valid Stage 4 fu'ivla, but xaceru looks like a sequence of cmavo, and kobra like a gismu.

For another example, integral has a specific meaning to a mathematician. But the Lojban fu'ivla integrale, which is a valid Stage 4 fu'ivla, does not convey that mathematical sense to a non-mathematical listener, even one with an English-speaking background; its source – the English word integral – has various other specialized meanings in other fields.

Left uncontrolled, integrale almost certainly would eventually come to mean the same collection of loosely related concepts that English associates with integral, with only the context to indicate (possibly) that the mathematical term is meant.

The prefix method would render the mathematical concept as cmacrntegrale, if the i of integrale is removed, or something like cmacrnintegrale, if a new consonant is added to the beginning; cmac- is the rafsi for cmaci (mathematics). The architectural sense of integral might be conveyed with dinjrnintegrale or tarmrnintegrale, where dinju and tarmi mean building and form respectively.

Here are some fu'ivla representing cultures and related things, shown with more than one rafsi prefix:

Example 4.52. 

ban,gr,blgara

Bulgarian (in language)


Example 4.53. 

kul,nr,blgara

Bulgarian (in culture)


Example 4.54. 

gug,dr,blgara

Bulgaria (the country)


Example 4.55. 

ban,gr,kore'a

Korean (the language)


Example 4.56. 

kul,nr,kore'a

Korean (the culture)


Note the apostrophes in Example 4.55 and Example 4.56, used because ea is not a valid diphthong in Lojban. Arguably, some form of the native name Chosen should have been used instead of the internationally known Korea; this is a recurring problem in all borrowings. In general, it is better to use the native name unless using it will severely impede understanding: Navajo is far more widely known than Dine'e.
