InflClass: inflectional class

Values: IndEurA IndEurO IndEurX IndEurI IndEurU IndEurE LatPron LatA LatE LatX LatI LatI2 LatAnom Ind

Latin distinguishes two main types of inflections: nominal and verbal.

Nominal inflection is traditionally called declension and applies to (proper) nouns, adjectives, pronouns, determiners and numerals, and can express gender, number, case and degree. It also applies to nominal forms of verbs, for which an additional layer is used.

Verbal inflection is traditionally called conjugation and applies to finite and nominal forms of verbs and the auxiliary sum, and can express aspect, mood, tense, voice, person, number and nominal form.

Adverbs, adpositions, co-ordinating and subordinating conjunctions, the various particles and interjections are all invariable parts of speech and never inflect in Latin.

Nominal and verbal inflections are themselves respectively subdivided into different declension and conjugation classes, which historically result from the development of Latin from Proto-Indo-European and were determined by phonological and analogical processes. Basically, the endings of a class were shaped by the final consonant or vowel of the original stem, and parallel outcomes can be observed, synchronically or diachronically, in most of the other Indo-European branches.

The values of InflClass reflect the original endings of the stems where possible; moreover, the string IndEur is prepended to those classes which have parallels in other Indo-European languages (hopefully making them reusable by other treebanks, too), while Lat specifies a class whose pattern is probably confined to Latin (and its daughter languages) only.

The class Ind for indeclinable words is universal (as it is a sort of “non-class”), and is only applied to members of part-of-speech classes which protoypically inflect, but not to protoypically invariable elements (such as conjunctions).

InflClass is kept distinct from NounClass (used for Bantu languages), because the latter involves agreement between a phrasal head and its dependents. On the contrary, inflectional classes in Latin are orthogonal to grammatical categories such as gender, tense, etc., although some correlations exist.

Some Latin words inherit Greek inflectional classes: these are assigned to an existing InflClass, but marked for Variant=Greek.

(Remark: Locative is not shown in the following tables, as it is marginal in the case system.)

IndEurA: first declension

Originating from stems terminating in -a. Mostly tied to the feminine gender, but a relevant portion of first-declension masculine nouns exist. First-class adjectives (including perfect and future participles and gerundives) and all superlative forms follow the first declension in the feminine.

Case Singular Plural
Nominative rosă rosae
Genitive rosae rosarum
Dative rosae rosis
Accusative rosam rosas
Vocative rosă rosae
Ablative rosā rosis

In other Indo-European branches: gr. θάλασσα, icel. borg, lith. gatvė

Examples

IndEurO: second declension

Originating from stems terminating in -e/o. Mostly tied to the masculine and neuter genders, but some feminine nouns in -us (mostly tree names) exist. First-class adjectives (including perfect and future participles and gerundives/gerunds) and all superlative forms follow the second declension in the masculine and neuter.

Case Singular Plural Singular Plural
Nominative lupus lupi templum templa
Genitive lupi luporum templi templorum
Dative lupo lupis templo templis
Accusative lupum lupos templum templa
Vocative lupe lupi templum templa
Ablative lupo lupis templo templis

In other Indo-European branches: gr. άνθρωπος, icel. íslenskur, lith. miškas

Examples

IndEurX: third declension (consonant stems)

Originating from stems terminating in a consonant (“athematic”). Every gender is represented. Pretty much confined to nouns and comparative forms, with few second-class adjectives represented.

Case Singular Plural Singular Plural
Nominative rex reges tempus tempora
Genitive regis regum temporis temporum
Dative regi regibus tempori temporibus
Accusative regem reges tempus tempora
Vocative rex reges tempus tempora

In other Indo-European branches: gr. θώραξ, icel. maður, lith. sesuo

Examples

IndEurI: third declension (i stems)

Originating from stems terminating in -i. Every gender is represented. Nearly all second-class adjectives (including present participles), some determiners and some numerals also follow this declension.

Case Singular Plural Singular Plural
Nominative ciuis ciues animal animalia
Genitive ciuis ciuium animalis animalium
Dative ciui ciuibus animali animalibus
Accusative ciuem ciues animal animalia
Vocative ciuis ciues animal animalia
Ablative ciue ciuibus animali animalibus

Examples

IndEurU: fourth declension

Originating from stems terminating in -u. Mostly tied to the masculine, but some feminine nouns in -us and neuter nouns in -u exist. Pretty much confined to nouns and the supine.

Case Singular Plural Singular Plural
Nominative fructŭs fructūs cornū cornua
Genitive fructūs fructuum cornūs cornuum
Dative fructui fructibus cornui cornibus
Accusative fructŭm fructūs cornū cornua
Vocative fructŭs fructūs cornū cornua
Ablative fructū fructibus cornū cornibus

In other Indo-European branches: lith. Vilnius

Examples

IndEurE: fifth declension

Originating from stems terminating in -e. Pretty much restricted to feminine nouns.

Case Singular Plural
Nominative res res
Genitive rei rerum
Dative rei rebus
Accusative rem res
Vocative res res
Ablative re rebus

Examples

LatPron: pronominal declension

Restricted to most of the (non-personal) pronouns and determiners. It is very similar (and clearly correlated) to the alternation between IndEurA (“first”) and IndEurO (“second”) declensions found in first-class adjectives, but deviates from it principally under the following aspects:

Many words belonging to this inflectional class also (or, in some cases, only) appear with a clitic-like suffix adjoined to the inflected form, and which contributes to semantic or pragmatic nuances (e.g. eadem ‘the same (one)’ with respect to ea ‘she’), like emphasis.

In future, this inflectional class may be revised and limited only to deviant forms, whith the others taking a “regular” IndEurA, IndEurO or IndEurI value.

Case Singular Plural
Nominative qui, quae, quod qui, quae, quae
Genitive cuius quorum, quarum, quorum
Dative cui quibus
Accusative quem, quam, quod quos, quas, quae
Ablative quo, qua, quo quibus

LatAnom: anomalous inflection

Some inflectional patterns, especially of some verbs and personal pronouns, show irregularities that cannot be fully traced back to other classes, and are therefore labelled as “anomalous” (as in uerbum anomalum, i.e. ‘irregular verb’).

Case Singular Plural
Nominative ego nos
(Genitive mei nostri)
Dative mihi nobis
Accusative me nos
Ablative me nobis

(nos ‘we’ can be also directly lemmatised as nos.)

Tense & Mood / Nominal form  
Present indicative uis
Past indicative uolebas
Future indicative uoles
Present subjunctive uelis
Past subjunctive uelles
Present participle uolens
Infinitive uelle

Examples

There are no anomalous nouns (including proper nouns), adjectives, or determiners: when not simply indeclinable (see Ind), their deviant forms can unproblematically be considered just variants inside their inflectional paradigms (e.g. animabus instead of animis for the plural dative/ablative of anima, first declension).

Ind: indeclinable (deprecated)

A word belonging to a part of speech whose members are usually expected to inflect, but which itself does not (or is never attested in more than one form), receives the value Ind. At the same time, it is not marked for case, but it might still retain gender and/or number if it is a (proper) noun, and thus possesses one inherently and not relationally. The infinitives, as verbal nouns, are indeclinable.

Most nominal parts of speech are also represented by some indeclinable members to a greater or lesser extent. It is not uncommon for these latter, especially for nouns, to be foreign loanwords. Sometimes, such words appear both as indeclinable and as inflected forms (e.g. Adam can be either indeclinable, or associated which the first declension, taking genitive Adae etc.).

The use of this value is deprecated and no longer implemented, as definitions by negative in general in UD: InflClass=Ind is actually not an inflectional class, but rather the absence of one. So, simply, nothing needs to be annotated, similarly to positive degree or positive polarity.

Examples

There seem to be no indeclinable finite forms of verbs nor pronouns.
