Dialectal variations are more noticeable in Chastuvien than in Genistien. The principal split is between the more conservative southern dialects of the peninsulas and islands and the more innovative northern coastal dialects, many of which are influenced by Genistien and Dekavurian.
The late Liotan falling diphthongs became long vowels in Chastuvien, often preceded by a glide; the original rising diphthongs became short vowels preceded by a glide. For example:
| Liotan | meaning | late Liotan | Chastuvien |
| ceóirr | taste | tSoirTe | chwérthe |
| caonh | fish | keunza | kyóndza |
| dán | father | dauna | dóna |
| siail | first | Sjele | shyele |
| buagh | goat | waGa | wagha |
| éimh | fear | eimve | yémve |
In general, /ei oi/ and /eu ou/ became /je: we:/ and /jo: wo:/, while /ai au/ merged with /e: o:/.

| Voiceless stops | p | t | ts | tS | k |
| Voiced stops | b | d | dz | dZ | g |
| Voiceless fricatives | f | T | s | S | x |
| Voiced fricatives | v |   | z | Z | G |
are the nasals /m n/, liquids /l r/, glides /w j/, and /h/. /ts dz tS dZ/ are, of course, affricates, which derived from slender /t d k g/ respectively; they are transcribed TS DZ SH J, as in oit "strong" > otse. The other consonants are transcribed as in Genistien, thus TH SH ZH GH for /T S Z G/ and W Y for /w j/.

| Broad | ju: | u: | o: | a | t | d | k | g | s | z | w | x | w | G | rx |
| Slender | i: | wi: | e: | e | ts | dz | tS | dZ | S | Z | f | j | v | j | rT |
More complicated are the alternations resulting from older short vowels preceding lenited /n m/ or unlenited /l/. Lenited /n/ gave rise to /a ~ (j)e:/, /i ~ i:/, /o ~ we:/, and /u ~ wi:/, while the other two caused /o: ~ a or e/, /iu ~ i/, /uo: ~ o/, and /u: ~ u/; unlenited /l/ also caused /T ~ l/. For example:
| Liotan | Broad | Slender |
| dán | dóna "father" | dénan "fathers" |
| maoc | myóka "sweet (masculine)" | myéche feminine |
| siadha- | shyazar "I live" | shyezhesh "you (def sing) live" |
| conh | kondza "pure (masculine)" | kwénje (feminine) |
| greamh | zhdrómva "loud (masculine)" | zhdremve (feminine) |
| poill | pwólo "short (neuter) | potha (masculine) |
In the northern dialects, the alternations in vowel length are usually levelled in favour of the long vowel; for example, potha became pótha under the influence of the neuter.
/j/ is often dropped in speech after /S Z tS dZ/, and both glides sometimes disappear after clusters of obstruent + liquid.
Clusters of four consonants, always of the form sibilant + stop + liquid + glide, sometimes appear at the beginning of a word, for example zhdrwóxa "what sort of?" with initial /Zdrw/. In such clusters, the glide is often dropped in speech.
| Case | Singular | Plural 1 | Plural 2 |
| Nom | tura | turane | turata |
| Gen | turan | turanen | turanta |
| Part | turas | turasta | turasta |
The "plural 1" endings are original, and are confined to southern dialects. The "plural 2" endings, which developed from the generalisation of the -ta of the partitive, are northern innovations identical in origin with the Astarien plural marker and the Genistien partitive plurals.
In some northern dialects, after a nasal, liquid, or fricative other than /T D/, the vowel before the nominative plural ending is often lost; thus swenita is often pronounced /swenta/. The /t/ voices to /d/ after a voiced consonant, as in /waGda/ for waghata "goats".
When a particular eye is referred to, the noun is prefixed with chi- and lo-, respectively from older words for "left" and "right". The plural of tsyara is tsyérine, "pairs of eyes", semantically equivalent to jyumane "mouths". tsyére, the direct descendant of the original Liotan singular téir, is only used when speaking of an eye which is not part of a pair, or when used figuratively to refer to, for example, the opening of a cave.
Similarly, gyóla refer to both parents together, but is syntactically a singular; "father" and "mother", however, are individually always swana nwóne, not rithe-gyóla, which refers to either parent indiscriminately, and certainly not *chi-gyóla or *lo-gyóla!
| Meaning | Masc | Fem | Neut |
| sweet | myóka | myétce | myóko |
| another | metca | metce | mako |
| narrow | wartha | warthe | warxo |
| fertile | chetsa | chetse | chato |
Attributive adjectives always follow the noun they qualified, thus tyóka myóka "a sweet apple", tyókane myókane "sweet apples".
The comparitives are formed with -um- -asht- -arh- suffixed to the masculine stem: myókume "sweeter (feminine)", chetsashta "not as fertile", wartharha "as narrow as". The equative -arh- becomes -arth- in the feminine: myókarthe "as sweet as".
Adverbs are expressed with la plus the adjective, which agrees with the subject of the verb: kandza el la myéche "she sings sweetly", but kandza an la myóka "he sings sweetly".
The demonstratives all replace the article, and are syntactically adjectives. Their nominative singulars are masculine chema kaha korha, feminine cheme kahe korthe, and neuter chemo kaho korho; the other cases and numbers decline accordingly: chemasta waghasta "these goats (partitive).

Chastuvien is alone in South Liotic in retaining prepositional pronouns, although the forms are not continued from Liotan. The pronominal forms with the basic pronons are:
| Person | "to" | "at" | "from" | |||
| 1 | ras | radza | nos | nodza | mes | medza |
| 2 def | rath | rava | noth | nova | meth | meva |
| 2 fam | ram | rama | nom | noma | mem | mema |
| 3 masc | rán | ránta | nwan | nwanta | myan | myanta |
| 3 fem | rél | rélta | nwel | nwelta | myel | myelta |
| 3 neut | rór | rórta | nwor | nworta | myor | myorta |
| 3 gen | rál | rén | nual | nwin | myal | mín |
| indef | rah | --- | noh | --- | meh | --- |
| rel | ras | --- | nos | --- | mes | --- |
| refl | raf | --- | nof | --- | mef | --- |
Other prepositions combine straightforwardly: tseras "onto me", tsenwin "on them", tsemyor "off it". Prepositions do not combine with the article.
The various forms of "here", "there", "yonder" are simple compounds of yemve aha orha and the appropriate prepositions: ra yemve "hither", me aha "thence".

Here are the present tenses of "gives" (first conjugation) and "does" (fifth conjugation), showing the distribution of the thematic vowels and, in the fifth conjugation, the alternations in the final consonant of the stem.
| Person | Singular | Plural | Singular | Plural |

| 3 | marun | maruna | bezan | bezana |
| indef | maruh | --- | bezah | --- |
| rel | marus | --- | bezas | --- |
| refl | marif | --- | bezhif | --- |
The past tense, negative, and interrogative, are formed with the same prefixes as in Genistein: e-marur "I gave", en-bezar "I did", the-marur "I do not give", then-bezar "I did not do", fi-marur "do I give?", fin-marur "did I give?".

| 8 | pore | por | porka | porkra |
| 9 | syóhta | syoh | syóka | syókra |
| 10 | kyédze | kyes | kyéska | kyékra |
The ordinal numbers probably derived from compounds with the indefinite pronoun ka.
The forms of phrases with the higher numbers are much the same as in Liotan, with the twenties, shime "400", and rene "8000" all requiring the partitive plural of the noun:
| Suffix | to | gave | meaning | examples |
| -sto | adj | noun | abstracts | myóka "sweet" > myókasto "sweetness", kondza "pure" > kondzasto "purity" |
| -ova | noun | adj | resembling, like | wagha "goat" > wagova "goatlike", gwene "girl" > gwanova "girlish" |
| -ola | noun | adj | lacking | chwérthe "taste" > chwórhola "tasteless", fanda "tree" > fandola "treeless" |
| -ivra | noun | adj | having, full of | yasta "breeze, wind" > yechtivra "windy", rata "mouse" > retsivra "full of mice" |
| -oza | verb | adj | -able | tyórhah "sees" > tyórhoza "visible", maruh "gives" > maroza "givable" |
| -ahta | verb, noun | noun | place | uneh "eats" > unahta "eating house", kathe "dog" > kathahta "kennel" |
Personal nouns are common in Chastuvien, for example kandzan kandzel kandzin "singer, singers". The inflections are, however, much more straightforward than those of Genistien, and parallel the pronouns exactly.
The only augmentative suffix in Chastuvien is -ad, which tends to have negative connotations: jiumadan "person who talks too much", from jiuma "mouth".
The commonest diminutive suffixes are, in decreasing order of affection, -ishe -iche -ile -ilche.
