Arpien

My first new conlang in 48 years!

No phonology yet, so of course no vocabulary yet.

It has 22 "open" word-classes and 80 "closed" word-classes.

The words "open" and "closed" are in quotes, because the real difference is that wherever an "open" word-class can be used, certain phrases can also be used there and be equally grammatical; but where a word from a "closed" class can be used, only another word from the same class can be substituted for it and still have a grammatical utterance.

It's completely isolating, and so it has no "morphology".

Its syntax can be written in Chomsky normal form.

It is entirely head-final.

Every phrase consists of two parts; the complement and the head.

The head determines both the word-class that the complement has to come from, and the word-class that the entire phrase can be substituted for.

OTOH if you know both the word-class of the complement and the word-class whose distribution the entire phrase's distribution matches, then you know the word-class the head must be from.

It is neither right-branching nor left-branching, since, when the head happens to come from one of the 22 "open" word-classes, it could be phrasal, even if the complement isn't phrasal. OTOH the head might be a single word (and, if it comes from one of the 80 "closed" classes, actually [u][i]must[/i][/u] be a single word), but the complement might be a phrase. In either case the head would still have to come after the complement.

I will publish a list of the word-classes, and the CFG grammar, when I get around to it, which I hope will be soon (but who knows?).

The purpose of this conlang is just to see whether or not I can actually make a conlang according to this formalism.

The capital letters are nonterminal symbols; they can be replaced by another non-terminal or by a string of non-terminals. The lowercase letters and numerics are "quasiterminal" or "metaterminal" symbols; they can be replaced by single words of the appropriate class, which are the terminal symbols. The lowercase letters represent "open" word-classes, and the numerics represent "closed" word-classes.

"A" represents sentences and/or clauses. "B" represents nouns and noun-phrases and phrases which can be used as if they were nouns.

I haven't decided on the exact correspondence between the usual terms for word-classes and the terms I'll use when talking about Arpien. But here's my first, partial, approximation.

A	Sentence or Clause B	Noun or Noun Phrase C	Auxiliary or Sentential Adverb D	Monovalent Verb or Verb Phrase (including most intransitive verbs) E	Complementizer or Phrasal Complementizer F	Adjective or Adjective Phrase G	Makes a Clause out of an Auxiliary or Sentential Adverb H	Makes a Clause out of a Monovalent Verb I	Makes a Clause out of a Complementizer J	Makes a Clause out of an Adjective K	Makes a Nominal Phrase out of an Auxiliary or Sentential Adverb L	Infinitivizer; Makes a Noun out of a Monovalent Verb M	Makes a Noun out of a Complementizer N	Makes a Noun out of an Adjective O	Conjunction for Clauses, or, Subordinator for Adjunct Clauses (resulting phrase modifies a sentence or clause) P	Bivalent Verb Taking a Noun and a Complement Clause; or Postposition (resulting phrase acts as an auxiliary or as a sentential adverb) Q	Subordinator for Adjunct Clauses (resulting phrase modifies a monovalent verb or verb phrase) R	Bivalent Verb or Verb Phrase (including most monotransitive verbs) S	Makes a clause into a complementizer T	Postposition Resulting in Phrasal Complementizer U	Relativizer V	Postposition Resulting in Phrasal Adjective; e,g, Genitive Postposition; or, Conjunction for Nouns 1	Adverb that Modifies an Auxiliary or Sentential Adverb 2	Makes an Auxiliary or Sentential Adverb out of a Monovalent Verb 3	Makes an Auxiliary or Sentential Adverb out of a Complementizer 4	Makes a Complementizer out of an Adjective 5	Makes a Subordinator out of an Auxiliary or Sentential Adverb 6	Adverb that Modifies a Monovalent Verb 7	Makes a Monovalent Verb out of a Complementizer 8	Makes a Monovalent Verb out of an Adjective 9	Makes a Complementizer out of an Auxiliary or Sentential Adverb 10	Makes a Complementizer out of a Monovalent Verb 11	Adverb that Modifies a Complementizer 12	Makes a Complementizer out of an Adjective 13	Makes a Phrasal Adjective out of an Auxiliary or Sentential Adverb 14	Participlizer; Makes an Adjective of a Monovalent Verb 15	Makes an Adjective out of a Complementizer 16	Adverb that Modifies an Adjective 67	Trivalent Verb Requiring a Noun and Two Complement Clauses 68	Trivalent Verb Requiring Two Nouns and a Complement Clause 69	Trivalent Verb Requiring a Noun and Two Complement Clauses 70	Trivalent Verb Requiring Two Nouns and a Complement Clause 71	Trivalent Verb Requiring Two Nouns and a Complement Clause 72	Trivalent Verb (Including Most Ditransitive Verbs)
