Linguistic typology is the typology that classifies languages by their features. Linguistic typology includes morphological, syntactic (sometimes "morphosyntactic"), and phonological typology. Typological classification of languages contrasts with the more familiar genetic classification into families that share an ancestor language (see historical linguistics). A genetic class is a language family, while a typological class is a language type. Research on typology often overlaps with research on linguistic universals.

Typological systems

[edit]

Agent-Verb-Object positioning

One set of types is determined by the basic order of agent (transitive 'subject'), verb, and object in sentences:

These are usually abbreviated AVO and so forth (or often SVO etc., with S for "subject"), and may be called "typologies" of the languages to which they apply. The use of the word 'subject' is somewhat misleading, even for languages which have subjects, because the SV or VS order of intransitive verbs does not in general follow the AVO etc. order of transitive verbs, as for example is the case with Russian.

Some languages split verbs into an auxiliary and an infinitive or participle, and put the agent or object between them. For instance, German ("Im Wald habe ich einen Fuchs gesehen" - *"In-the wood have I a fox seen"), Dutch ("Hans vermoedde dat Jan Piet Marie zag leren zwemmen" - *"Hans suspected that Jan Piet Marie saw teach swim") and Welsh ("Mae'r gwirio sillafu wedi'i gwblhau" - *"Is the check spelling after to complete"). In this case, typology is based on the non-analytic tenses (i.e. those sentences in which the verb is not split) or the position of the auxiliary. German is thus AVO/VAO (without "im Wald" the agent would go first) in main clauses and Welsh is VAO (and O would go after the infinitive).

Both German and Dutch are often classified as V2 languages, as the verb invariantly occurs as the second element of a full clause.

Some languages that are inflected are difficult to classify in the AVO typological system, because virtually any ordering of verb, object, and agent is possible and correct. All we can do for such languages is find out which word order is the most frequent. For example, in a non-inflected language, the agent and object of a sentence are determined by word order; in an inflected language, the determination may be made by affixes applied to nouns to designate their grammatical roles. In such a system, fixed word order is not necessary to determine meaning (although highly inflected languages do sometimes develop normative word orders). Inflected languages without a fixed word order include Latin, Polish, and Greek.

Ergative-accusative

Another common classification is according to whether a language is accusative or ergative. In a language with cases, the classification depends on whether the subject of an intransitive verb has the same case as the agent or the object of a transitive verb. If a language has no cases, but is AVO or OVA, then a classification may be based on whether the subject of an intransitive verb is on the same side as the agent or the object of the transitive verb.

Many languages show mixed accusative and ergative behaviour (e.g. ergative morphology marking the verb arguments, on top of an accusative syntax). Other languages (called "active languages") have two types of intransitive verbs—some of them ("active verbs") join the subject in the same case as the agent of a transitive verb, and the rest ("stative verbs") join the subject in the same case as the object. Yet other languages behave ergatively only in some contexts (this is called split ergativity, and is usually based on the grammatical person of the arguments or in the tense/aspect of the verb). For example, only some verbs in Georgian behave this way, and, as a rule, only while the tense called aorist is used.
