Teaching LH/CG Characters, OCs, and Others About Conlanging

Ideas for a Demo(Part 2)

I need to also work out the grammar and syntax in advance. Here are the ideas.

PIE-esque Word Order: SOV

PS-esque Word Order: VSO

PIE-esque Syntax: adjectives before nouns, prepositions

PS-esque Syntax: adjectives are derived from both nouns and verbs with limited use, prepositions

PIE-esque Gender: masculine and feminine(and maybe neuter?), or common and neuter

PS-esque Gender: masculine and feminine

PIE-esque Number: singular, dual, and plural

PS-esque Number: singular, dual, and plural

PIE-esque Tenses: past and non-past(present)

PS-esque Tenses: past(imperfect) and non-past(present)

PIE-esque Aspects: imperfective("present"), perfective("aorist"), and stative("perfect")

PS-esque Aspects: ???

PIE-esque Moods: indicative, imperative, subjunctive, and optative

PS-esque Moods: imperative

PIE-esque Passive: none

PS-esque Passive: unknown

PIE-esque Causative: none

PS-esque Causative: prefix

Can't find anything on the original PIE and Proto-Semitic about reconstructed valency-changing operations.

PIE-esque Copula: prefix meaning "(to) be"

PS-esque Copula: none

PIE-esque Noun Cases: nominative, accusative, genitive, dative, instrumental, ablative, locative, and vocative(and maybe allative?)

PS-esque Noun Cases: nominative, accusative, and genitive

PIE-esque Articles: none

PS-esque Articles: none

PIE-esque Demonstratives: https://www.wikiwand.com/en/Proto-Indo-European_pronouns#Demonstrative_pronouns

PS-esque Demonstratives: https://www.wikiwand.com/en/Proto-Semitic_language#Pronouns

PIE-esque Persons: 1st, 2nd, and 3rd

PS-esque Persons: 1st, 2nd, and 3rd

PIE-esque Clusivity: none

PS-esque Clusivity: none

With this information, there could be a lot of speculation about the proto-grammar that these two sets could be the evolved forms of. Either the protolang possessed a copula that the Proto-Semitic-inspired one lost, or it never did and the PIE-inspired one evolved it. Though I wonder what else reconstructions of PIE and Proto-Semitic had that I could modify for these spin-off versions. And I would also know what those grammatical features would've evolved from if they were found in other languages.

What do you think?

Now for those other three languages.

Seri-esque Word Order: SOV

Osage-esque Word Order: SOV

Ewe-esque Word Order: SVO

Seri-esque Syntax: adjectives derived from verbs, postpositions

Osage-esque Syntax: adjectives after nouns, postpositions

Ewe-esque Syntax: adjectives after nouns, postpositions
