Pragmatic word order

In linguistics, word order typology is the study of the order of the syntactic constituents of a language, and how different languages can employ different orders. Correlations between orders found in different syntactic sub-domains are also of interest. The primary word orders that are of interest are the constituent order of a clause – the relative order of subject, object, and verb; the order of modifiers (adjectives, numerals, demonstratives, possessives, and adjuncts) in a noun phrase; and the order of adverbials.

Some languages use relatively restrictive word order, often relying on the order of constituents to convey important grammatical information. Others—often those that convey grammatical information through inflection—allow more flexibility, which can be used to encode pragmatic information such as topicalisation or focus. Most languages, however, have a preferred word order, and other word orders, if used, are considered "marked".

Most nominative–accusative languages—which have a major word class of nouns and clauses that include subject and object—define constituent word order in terms of the finite verb (V) and its arguments, the subject (S), and object (O).

There are six theoretically possible basic word orders for the transitive sentence. The overwhelming majority of the world's languages are either subject–verb–object (SVO) or subject–object–verb (SOV), with a much smaller but still significant portion using verb–subject–object (VSO) word order. The remaining three arrangements are exceptionally rare, with verb–object–subject (VOS) being slightly more common than object–subject–verb (OSV), and object–verb–subject (OVS) being significantly more rare than the two preceding orders.
