Primal's grammar makes it a VBL (verb-based language). There's probably some technical term for this, but I've never seen it.
The conjugations of verbs are entirely regular, but the nouns, adjectives, participles, and adverbs (derived from the verbs) have some variation.
The rest of this page is a list of links, not all of which are up yet.
Verbal Conjugations- This page illustrates the conjugations used by Primal verbs, using the verb "morolo" (to walk). Primal conjugates by using inflections, which convey tense, mood, number, and sometimes aspect.
A and AA verbs- The first class of Primal verbs, those ending with the soft ah sound, and the rules for deriving nouns and so on from them.
E, AI, and UE verbs- The second class of Primal verbs, those ending with the strong a sound.
I, UI, and OI verbs- The third class of Primal verbs, ending with the ee, wee, and oy sounds.
O verbs- The fourth class of Primal verbs, ending with the oh sound.
U, OU, and AU verbs- The fifth class of Primal verbs, ending with the oo, ow, and awe sounds.
Y, YY, AE, AY, EY, and EI verbs- The sixth class of Primal verbs, ending with the i, ii, and long a sounds.
UU verbs- Highly irregular verbs ending with the oo-oo sounds.
Irregular verbs- Verbs utterly irregular in their noun formation.
Cases- Primal has six cases, though no irregularities.
Syntax- Primal syntax, or word order, is not a very big part of the language, given its reliance on inflection, but there are some elementary rules to be followed.
Blending- Primal tends to put smaller words together to achieve larger ones, and the words will sometimes blend when it does so. These are the rules for the blending.
Pronouns- Some special notes on Primal pronouns.
Obscure Words and Tenses- There are some Primal words and tenses that are not used very often, but may be included in governmental speech or poetry, to which Primal, depending on the Age of Arcadia, is sometimes confined. These are notes on those.
