Let me introduce my conlang

My conlang is called Senyecan, "ancient language," although a name
was needed only when other languages began to develop.  The start of
the lexicon is Pokorny's book, added to or modified by my research.
Since it is the "first" language, the grammar is as simple as
possible.  There are virtually no exceptions or irregularities.  It
is an isolating (analytic) language; the only inflection is a simple
nominal declension: 3 cases for nouns & adjectives, nominative,
motive & stative.  Motive = motion indicated; stative = lack of
motion.  It is SOV so ALL modifiers precede.  Postpositions.  There
are currently 1831 basic words & numerous derivatives.

Verbs are marked only for mood & must be preceded by a subject
pronoun.  There is only a present tense, prefixed augments being used
for past & future, reduplication for perfective aspect.  The verb is
seen as the basic element of the language.  CVC roots form the verbs
on which almost all the derivatve words are formed.

There are 6 loquent peoples, so 6 is a mystical number for them.
There are 30 phonemes: 24 consonants & 6 vowels.  Four places of
articulation (labial, dental, alveolar & palatal), 3 manners of
articulation (plosive, fricative & sonorant), 4 x 3 = 12.  Each one
paired voiced & voiceless = 24.  I recently discovered a site for IPA
sounds, so I'm rethinking the 6 vowels.  Senyecan is also tonal.
Verbs, nouns & adjectives have a primary tone on a high pitch. If
there are 4 or more syllables there is a secondary tone on a medium
pitch.  The other syllables have a basal tone which is a low pitch.
Polysyllabic words in other classes only have secondary and basal
pitch.

There are 3 scripts: a rectilinear for carving in wood and stone, a
cursive derived from them, & one suitable for use with a brush
derived from the cursive.  I write the language with a modified Latin
alphabet.  However, the native speakers of today prefer the Cyrillic
alphabet.

Besides a dicionary and a grammar, I have a list of the fauna and
flora available to me, a pharmacopeia, a table of correlatives, a
kinship tree, the Swadesh list, & various & sundry other works.  I
have also done the requisite translation of the Tower of Babel story!

That should do it for a start.

BTW, my Russian grammar lists the cases in the order: nom., gen.,
dat., acc., inst., & prep.
