[35] Feminine nouns ending in non-alternating consonants always add ⟨-j-⟩ to non-nominative cases except the genitive plural, which takes -∅.
[73] One can generally predict when alternations take place for each inflection type knowing the gender, number of syllables of the stem, last stem vowel, the voicedness of the final consonant (⟨-ôù⟩ is considered voiced), and whether stress is mobile or stressed.
If the genitive plural is -∅, then ⟨o, ó, é, y, ú, õ, ˈôù, ˈôj, ŭ⟩ are present.
[75] Nouns ending in a consonant alternate only if the vowel in the final stem syllable is ⟨o, ó, é, y, ú, õ, ˈôù, ˈôj, ŭ⟩.
[74] ⟨o, ó, é, y, ú, õ, ˈôù, ˈôj, ŭ⟩ ~ ⟨a, ô, e, ë, i, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩ alternate for neuter polysyllabic stems ending in a consonant ending with ⟨-ô⟩ in no singular forms and in all plural and dual forms.
If the genitive plural is -∅, then ⟨o, ó, é, y, ú, õ, ˈôù, ˈôj, ŭ⟩ are present.
⟨ˈa, a; ˈô, ô; ó, o⟩ may change into ⟨ˈê⟩ when stressed and ⟨ê⟩ when unstressed in native monosyllabic or polysyllabic stems.
[114] The short masculine/neuter genitive form and ⟨-o⟩ is most often found with adjectives that do not have a stress on the final syllable, especially when they are used as nouns.
⟨-é⟩ causes consonant softening: ⟨p, b, w, m, t, d, st, zd, n, k, g, ch, r⟩ alternate with ⟨pj, bj, wj, mj, c, dz, szcz, żdż, nj, cz, ż, sz, rz⟩.
), hundreds, and thousands in Slovincian have a single word, all others are made through combining other cardinal numbers.
Numbers from five (pjˈync) to twenty (dwadzˈêsca) except word for "teens" ending in ⟨-e⟩ are declinable.
Conversely, the hundreds emphasize the number word; if this is polysyllabic, the following noun has a secondary accent.
The Slovincian future tense, perfect, pluperfect, conditional and passive form have periphrastic formations.
[156] The feminine singular and masculine dual contract in classes IB, IC, III1B—E, III2, IVB, IVC.
Class IVAa comprises verbs whose stems end in ⟨p, b, f, w, m, n, k, zg, j⟩, and IVAb in the remaining consonants.
[181] This class comprises nine base verbs (and their prefixed derivatives) which had the ending -m in the first person singular.
[183] Va includes verbs whose present tense roots do not have any special stem-forming element.
Class III2A (verbs in ⟨-ac⟩) show a regular stress shift onto the inflectional suffix in the third person plural.
This stress shift is rare in monosyllabic present forms with a V1, but there are many exceptions[196][197] Verbs also display three types of alternations.
[200] Class IA verbs show regular ⟨o, ó, é, y, ú, õ, ˈôù, ˈôj ŭ⟩ ~ ⟨a, ô, e, ë, i, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩ alternations; ⟨o, ó, é, y, ú, õ, ˈôù, ˈôj, ŭ⟩ in the infinitive and ⟨a, ô, e, ë, i, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩ everywhere else except the past masculine singular.
[200] Class IIC verbs with any alternation (not all have it) change ⟨o, ó, é, y, ú, õ, ˈôù, ˈôj, ŭ⟩ into ⟨a, ô, e, ë, i, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩ in the imperative and often in all l-forms where /-l/ isnˈt the final phoneme of the word.
[200] If verb has ⟨a, ô, e, ë, i, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩ as a stem vowel or a single vowel, verb classes IA (except lˈêsc ("to climb")), II, IIIA2, III2Ab, III2B, III2C, III2D, and IVB do not have a ⟨o, ó, é, y, ú, õ, ˈôù, ˈôj ŭ⟩ ~ ⟨a, ô, e, ë, y, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩ or ⟨a, ô, e, ë, y, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩~⟨o, ó, é, y, ú, õ, ˈôù, ˈôj, ŭ⟩ alternation in the forms with an inflectional suffix vowel, but all other verbs are split into alternating and non-alternating (with ⟨o, ó, é, y, ú, õ, ˈôù, ˈôj ŭ⟩ in the present and l-forms, and n-forms in the verbal noun) subclasses.
[200] The past tense always shows ⟨o, ó, é, y, ú, õ, ˈôù, ˈôj, ŭ⟩ in the masculine singular, ⟨a, ô, e, ë, i, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩ in all other cases except in classes IAa and IAc, where alternative forms with ⟨a, ô, e, ë, i, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩ can be found.
This results in regular ⟨o, ó, é, y, ú, õ, ˈôù, ˈôj, ŭ⟩ ~ ⟨a, ô, e, ë, y, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩ alternations.
[201] The infinitive can have either ⟨o, ó, é, y, ú, õ, ˈôù, ˈôj, ŭ⟩ or ⟨a, ô, e, ë, i, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩ in the final syllable.
Class III1A2a shows ⟨o, ó, é, y, ú, õ, ˈôù, ˈôj, ŭ⟩~⟨a, ô, e, ë, i, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩ alternation.
Classes IC, III1C, III1D, III1E, III2Aa, III2C, III2D, and IVC show the ⟨a, ô, e, ë, i, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩ of the infinitive for ⟨-n⟩ forms.
Class III1A2b shows ⟨o, ó, é, y, ú, õ, ˈôù, ˈôj, ŭ⟩~⟨a, ô, e, ë, i, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩ alternation.
The imperative and present tense acquire a special treatment only when there is one vowel in the verb.
[204] In the following verb classes the vowel show regular alternations in the imperative on the basis of the present tense forms if it is the only vowel in the verb:[204] Classes III2Ab and III2B show a regular alternation ⟨a, ô, e, ë, i, ã, ê, aj⟩ / ⟨ôˈù, ej, ĭ⟩~⟨o, ó, é, y, ú, õ, ˈôù, ˈôj, ŭ⟩ (⟨ˈê~éˈ⟩, the former in the present tense, the latter in the imperative.
