The diphthongs continue the late Liotan diphthongs; /iu io/ and /ui ue/ fell together with /eu/ and /oi/ respectively, while /ia ie/ and /ua uo/ merged with /e/ and /o/. The /oi/ in koishe "ill", boizha "hollow", and goinye "girl" thus derive respectively from /oi ui ue/ (in Liotan, cóis búigh guaine). The diphthongs only appear in stressed syllables; when unstressed, /ei ai oi/ are reduced to /e/ and /eu au ou/ become /o/.
/a/ in isolation is usually central, halfway between [a] and [A]; in the vicinity of front vowels it is closer to [a], and near back vowels it is closer to [A]. Thus kathe "dog" is approximately [ka:Te], while thoura "small" is /TourA/.
The distinction between /e o/ and /i u/ in unstressed syllables is neutralised to varying degrees in Ivrien; all varieties complete the merger word-finally, and the resulting vowels are transcribed E O here.
In stressed open syllables, i.e. those followed by a single consonant or a stop followed by a liquid, simple vowels are noticeably lengthened, often with a closer articulation. For example, the stressed /e/ in fela "quick" is lengthened and closed to [e:], by comparison with the unaltered [E] in fenda "tree". A consequence of this is that a stressed syllable may not contain an unchecked short vowel.

| Nasals | m | n |   | J | N |
| Laterals |   | l | l_0 | L |   |
| Trills |   | r | r_0 | r_j |   |
The consonants are transcribed in the same way as those of Kadhrein, with the addition of TH DH RY LH RH for /T D r_j l_0 r_0/. As the transcription indicates, /l_0 r_0/ are voiceless variants of /l r/, with the same place of articulation despite their place in the table.
As in Kadhrein, voiced stops became voiced fricatives between vowels, and /s/ was weakened to /h/ before a stop. The consonants referred to as "voiceless stop" above are thus actually strongly preaspirated intervocalically, continuing older clusters of /s/ + stop, while intervocalic "voiced stops" are always voiceless. The velar consonants in faka "friend", doga "crab", and pagha "bow", the Ivrien reflexes of fasg doc pag, thus represent /hk k G/ respectively, whereas the G in gushe "long" is simply /g/.
The liquids are devoiced before voiceless consonants; /lt/ is this [l_0t], compared with /ld/ which is [lt]; and also word-initially, as with lheuda "wood" and rhithe "half".

The permitted consonant clusters are the same as in Kadhrein.
The cases are the nominative, partitive, genitive, and vocative; the older dative case had fallen together with the nominative. The vocative, as in Liotan and Machren, prefixes a-H: a-ghaula "O man!". The nominative and partitive are formed with suffixes as follows:
|   | Masculine | Feminine | Neuter | |||
| Case | Sing | Plur | Sing | Plur | Sing | Plur |
| Nominative | gaula | gaulan | eitye | eityen | roukho | roukhon |
| Partitive | gaulas | gaulanyas | eityes | eityenyas | roukhos | roukhonyas |
The genitive case is formed with a mutation, not a suffix. A noun in the genitive case always follows the noun it modified, and lenites its initial consonant if the dependant is singular and eclipses it if it is plural: eitye ghaula "man's house", eitye ngaula "man's houses".

| Plur | Nom | ke-H | ki-H | ke-H |
|   | Gen | ka-N | ke-N | ko-N |
|   | Part | kas-N | kes-N | kos-N |
Demonstrative particles, as in Kadhrein, follow the noun. The particles are em "this", akh "that", and or "yonder": ke eitye em "this house", eitye em "one of these houses".
| Case | Singular | Plural |
| Nominative | gaula lyoura | gaula dhouran |
| Partitive | gaula lyouras | gaula dhouranyas |
| Genitive | ghaula lyoura | ghaula dhouran |
| Vocative | a-ghaula lyoura | a-ghaula dhouran |
Adjectives decline for gender, and retain the original alternation between broad and slender consonants; in general, palatal consonants in the feminine typically alternate with a dental, alveolar, or velar in the neuter, while the masculine may use either. Some examples are shown below.
| Meaning | Masculine | Feminine | Neuter |
| "small" | thoura | thourye | thouro |
| "narrow" | bartha | barthe | barxo |
| "straight" | foula | foulye | foulo |
| "old, aged" | geitha | geithe | geilo |
| "new" | ouga | oudye | ougo |
As with the nouns, older vocalic alternations often give rise to doublets, such as geula "sacred, revered" and foilya "true, righteous" from geitha and foula.

The stressed genitives are the same as the stressed nominatives with lenition of the following noun: savra khathe "my dog", compared to sa-gkathe "my dog". The stressed partitive is formed by suffixing the final consonant of the unstressed partitive to the stressed nominative: savras devras and so on.
Possessive pronouns are formed by adding -nka to the genitive, (-ka after a consonant) and decline for case, number, and gender: sanka "mine", anka "his", elka "hers" (all masculine nominative singular), inkenyas "theirs" (feminine partitive plural).
The demonstrative pronouns are compounds of kavra and the demonstrative particles: kavrem "this one", kavrakh "that one", kavror "yonder one".
fa dya tya, respectively "from inside", "from outside" and "off", have longer and more formal forms fogha dyogha tyogha. rhe "to, towards", nyo "at", me "from, away from", be "through", and she "as far as, up to" were invariable.
The personal endings are added directly to the prepositions, thus nyovos "in front of me", menye "away from them". The genitives of these trigger the appropriate mutation on a following noun: shes vfenda "up to my tree".
The endings with the article are -kh in the singular and -sh in the plural, irrespective of gender. All prepositions trigger lenition in the singular and eclipsis in the plural, whether an article is present or not: nyovokh fhenda "in front of the tree", nyovosh vfendan "in front of the trees", nyovo vfenda "in front of some trees".
The locative forms of "here", "there", and "yonder" are emvo akho orkho, and the allative and ablative forms are similarly formed with -e -a, thus emve "hither" and akha "thence".
If the subject is a noun, an accompanying article is reduced to a suffix on the verb (-x in the singular and -c in the plural). However, since the subject in the original Liotan construction was in the dative case, in Ivrien it retaines its initial mutation, leniting in the singular and eclipsing in the plural. The endings on the sense-verb and the mutations on the subject noun are illustrated by the following.
|   | do | eich | ||
|   | Present | Past | Present | Past |
| Positive | doula- | sheila- | eula- | ezla- |
| Negative | thoula- | theila- | theula- | thezla- |
In speech, except in the past forms derived from eich, the -la is often dropped from these sense-verbs, thus dous for doulas.
|   | Present | Past |   | |||
| Meaning | Active | Passive | Active | Passive | Source | Vowels |
| "eat" | bunyelta | bunyidya | bunyishta | bunyeska | e | e i |
| "sit down" | mitelta | mitodya | mitoshta | miteska | e: | e o |
| "bend" | pazholta | pazhedya | pazheshta | pazhoska | o: | o e |
| "see" | terxalta | terxadya | terxashta | terxaska | a | a a |
| "do" | bezalta | bezhedya | bezheshta | bezhaska | mixed | a e |
| "give" | maryolta | maryidya | maryishta | maryoska | i: | o i |
| "learn" | dyilyulta | dyilyedya | dyilyeshta | dyilyuska | u: | u e |
The endings of the reduced forms are -l -sh -th -kh respectively, before which /i u/ become /e o/. Consonant alternations take place in the stem of verbs in the mixed conjugations, for example bezhedya and bezalta in the table.
| construction | tense | equivalent | notes |
| dou[la]s bunyel | unmarked present | "I am eating" | used when no special attention was drawn to the verb |
| dou[la]s bunyeth | present perfect | "I have eaten" | completed action with present relevance |
| shei[la]s bunyel | imperfect | "I was eating" | continuous action in the past |
| shei[la]s bunyeth | preterite | "I ate" | completed action in the past; theoretically a pluperfect, but never used as such |
| eu[la]s bunyel | habitual present | "I eat, I tend to eat" | also used for actions unbounded by time |
| ezlas bunyel | habitual past | "I used to eat, I tended to eat" | habitual actions in the past |
The passive participles are very rarely used with sense-verbs, and only when no verbal agent is present; dou[la]r bunyesh "it is being eaten" is more usually dou[la]kh bunyel or, with the impersonal form of the verb.
The past active participles (the ones in -th) are rarely used with the eich-derived sense-verbs, i.e. eu[la]s bunyeth and ezlas bunyeth are seldom heard.
The second construct is not used if the sense-verb derives from the past of eich.

The idiosyncratic nau, rather than the expected naf, was originally a dialectal pronunciation. mel "one" is a proper adjective, and triggers the appropriate mutation: mel teuga "one apple", mel ghoinye "one girl", mel ndyeuzo "one lie".
Other numbers follow the Liotan pattern:
| Suffix | to | gave | meaning | examples |
| -ato -eto | adj | noun | abstracts | thoura "small" > thourato "smallness", nyeitye "sweet" > nyeityeto "sweetness" |
| -ova | noun | adj | resembling, like | kenza "fish" > kenzova "fishy", teuga "apple" > teugova "apple-like" |
| -ola | noun | adj | lacking | thirxa "hair" > thirxola "hairless", filye "leaf" > filyola "leafless" |
| -ivra | noun | adj | having, full of | fenda "tree" > fendivra "covered in trees", thirkha "hair" > thirkhivra "hairy" |
| -oda | verb, noun, adj | noun | place | koishe "ill" > koishoda "sick-house, hospital", kathe "dog" > kathoda "kennel" |
Diminutives are formed with several suffixes, which often carry emotional or judgemental connotations. When added to nouns the gender of the original noun is preserved. For example:
Augmentative suffixes are fewer in number. The commonest is -oz-, for example etyoze "mansion, palace".
V1 S1 P1, V1 S1 P2 >> V1 S1 P1(pres act) P2
doukh ghoinye kanzal, doukh ghoinye benol nyovokh fhenda >>
doukh ghoinye khanzalta benol nyovokh fhenda
"The girl sings,
the girl is in front of the tree" >> "the singing girl is in front
of the tree"
In this example, the tenses of the sense-verbs of the two clauses are the same. If the sense-verb of the first clause is in the past tense ("the girl who sang"), the sentence uses the past participle khanzicta in place of khanzalta. Note that the participle is lenited because it is effectively an adjective modifying a singular noun; if many girls are referred to, ke ghoinye khanzalta becomes ki ghoinye gkanzalta, with eclipsis.
In the same example, if the relative clause is the longer of the two (i.e. "the girl who is in front of the tree is singing"), the result becomes doukh ghoinye venzulta nyovokh fhenda kanzal.
This construct is not used if the relative clause refers to a noun which was not the subject of the relative verb. Instead, the standard Liotan construct is used, with the conjunction a-H and the relative pronoun to or its inflection -th: douth benol nyovokh fhenda ke ghoinye a dhoulas terkhel to (with terkhel from "to see").
The combination of a with the basic sense-verbs is often reduced in speech to the following:
|   | do | eich | ||
|   | Present | Past | Present | Past |
| Positive | adha- | ashla- | aula- | azla- |
| Negative | ala- | aila- | a theula- | a thezla- |
doulas terkhel kanzalta ken ghoinye "I see the girl singing"
ei ke ghoinye adhath khanzel "It is the *girl" who is singing
gi ashlath khanzel "Who sang?"
