Tatediem: The "Grammatical Noun Class"

The noun class that I have termed "the grammatical class" has several important functions in Tatediem. Conjunctions, certain other particles, and quite a few adverbs are marked by it. Gerunds also are marked by it, and in some constructions numerals too.

The grammatical class prefixes are:
singular: re-, ur-
dual: rá-, ur-
plural: ráx-, ur-
mass: re-, ur-
where the rightmost is the object form, as well as the form that goes on adjectives. The ráx- form sometimes causes metathesis, e.g. rekém - rákxém (not at that time, never).

Gerunds are always marked by it:
regómn (from the verb stem gómn, guard) 'guarding, to guard'

With gerunds, using the dual or plural forms can be a way of indicating iterativeness or habituality:
ráxktìk (from the verb stem ktìk, rise) 'to rise often, repeated rising'
rábampù (from the verb stem bámpù, cook) 'twice cooking, to cook twice', but more specifically the preparation of a certain crop requires cooking it twice, and rábampù most specifically refers to the preparation of this crop.

As for adverbs, some lexemes take ur-, some take re- or even ráx-.

ráxtúim - certainly, surely, truly

urmá - quickly

rewrù - soon

rakxir -  for ever

ráŋum - again 

The demonstratives, when taking this set of prefixes go from being determiners to having a meaning closer to 'here', 'there', etc.

nebán nekús = this stick (note: the demonstratives use the same prefixes as the nouns, not the same as the adjectives)

rebán = here

sarján sartìpí = yonder mark, that mark (visible to the speaker and listener)

reján = (over) there

gemgán gemedùliŋ = those peaks

regán = in that place, there (a distant 'there')

Plural prefixes are possible, but unusual. "Raxbán raxgán" is a common expression for "all over the place". "Raxgán" sometimes is used to signify "lost, in an unknown place". The plurals may also be used to signify boundaries, i.e.
"ku-nitìsp rax-jàn k-u-(u)r-ùtur, ne-bán ne-timb, ses-jàn ses-kúmcé, sesjàn sesràm, gemgán gemegís"
neut1.sg-border gram.plur-there neut1sg-gram-stretch.along, masc-this masc-river, neut4-yon neut4-forest, neut4-yon neut4-road, neut3-that neut3-lake
The border stretches along these: this river, that forest, that road and the lake.

More later on the constructions with numerals, on particles and conjunctions as well as probably more adverbial stuff in general.
