Lojban vs Loglan comparison

For the Lojbanists interested in history: a grammatical comparison of Loglan vs Lojban

• terminology
  • prim(itive) = gismu (see also gismu != primitives)

• • borrowing = fu'ivla
  • complex, CPX = lujvo (hence pluja valsi)

• • metaphor = tanru
  • little word, LW = cmavo (hence cmalu valsi!)

• • affix = rafsi
  • lexeme = selma'o (in the extended sense)

• • GMR (Great Morphological Revolution) = introduction of rafsi system into the language (pre-split)
• Phonetics/Orthography

• • Vowels
    • diphthongs are ai, ei, oi, ao (= Lojban au)

• • • optional diphthongs are iV, uV
    • all other vowel pairs are pronounced with glides

• • • no equivalent of ', so no contrast like ai/a'i
  • Consonants

• • • role of x is taken by h
    • Extra letters (used only in names, borrowings):

• • • • x, pronounced as in Lojban
      • q, IPA T = English unvoiced "th"

• • • • w, IPA y = German �, French u
  • Capitalization follows the pattern standard for the European languages: used in the beginning of a sentence and for proper names. Nonstandard stress is marked by an apostrophe preceding the stressed syllable.

• Morphology
  • basically the same at time of split

• • Loglan has added a new rule: in any lujvo beginning CVCC, where CC is a permissible initial, change to CVCyC. This eliminates the need for the slinku'i test (according to TLI)
• Vocabulary

• • Gismu
    • formed on the same principles

• • • very different in detail due to different weights (much more English-y) and presence of h instead of x
    • see also Borrowing from Loglan

• • • see also The x2 place of blanu
  • Rafsi

• • • don't necessarily have just one of CVC, CCV, or CVV forms, but maximum is still three
  • Fu'ivla

• • • often use h-clusters to "solve" morphological problems (e.g. athomi = x1 is an atom)
  • Cmavo

• • • show various "sound law" changes, e.g. Loglan gu = Lojban ku (but much more general "universal" terminator), Loglan no = Lojban na, Loglan noi = Lojban nai, Loglan keks = Lojban geks, Loglan ceks = Lojban jeks.
• Grammar

• • masses/sets
  • abstraction

• • modals
  • tenses

• • relative clauses
  • Imperative

• • • formed by omitting the x1 argument
  • mekso

• • attitudinals
  • negation

• • termsets
  • Vocatives: hoi instead of doi (as in "rano, hoi Spat. I prano.")

• • ??? what else
• Usage/Style

• • sumti raising
