Proto-Draco

'''I, the author of this language, am a complete beginner in conlanging. I'd appreciate any input and help doing this.'''

'''In particular, I'm a native Brazilian Portuguese speaker, fluent in English, and most of my obvious grammar choices will be based on that. If anyone can then point me where it's "too Romance" or "too Germanic", that would be golden advice :)'''

Rheahar is a (totally WIP) proto-language sketch I'm working on (my first, in fact) to serve as a base for a draconic language (family) to use sparingly in a D&D adventure.

I intent to borrow some grammar cues from the "official draconic" that was published on the Dragon Magazine a few centuries ago (so far, only the fact that it has interesting possessive relationships, which feels dragon-like, but not the possessive relations themselves), but completely eschewing its not very dragon-sounding phonology and lexicon, and its god-awful letter-by-english-letter script.

Phonotactics
Syllables are C(L)V(V)(C). Onset can be any consonant; L must be a glide or liquid (/j/,/l/~/r/), and can only occur after a plosive, or the dental and alveolar fricatives; codas can be any consonant.

/ʀ/ only occurs at word start or intervocalically; /h/ only at word boundaries or intervocalically.

Nouns
Nouns are invariant, but preceding articles are mandatory, and these inflect by genre and case.

There is no grammatical number, but explicit quantity determiners (including "no", "few", "many", "all", "any", "some/unknown", etc.) can be agglutinated to articles.

Pronouns
Individual pronouns exist for the first and second persons (not differentiating number), and a first plural inclusive (not differentiating whether third parties are also included). There are no dedicated third person personal pronouns, and demonstrative pronouns are used for that role. Pronouns, both personal and demonstrative, inflect by case; demonstratives also inflect by genre.

Verbs
Verbs have two forms: verbal and predical. Verbal forms are used for indicative and imperative moods, and verbal phrases. The predical form is akin to a participle, and doubles as Rheahar's adjective.

Neither forms inflect. The role of participants is determined by case markings on the obligatory articles or pronouns.
