In linguistic typology, subject–verb–object (SVO) is a sentence structure where the subject comes first, the verb second, and the object third. Languages may be classified according to the dominant sequence of these elements in unmarked sentences (i.e., sentences in which an unusual word order is not used for emphasis). English is included in this group. An example is "Sam ate yogurt." The label often includes ergative languages that do not have subjects, but have an agent–verb–object (AVO) order. SVO is the second-most common order by number of known languages, after SOV. Together, SVO and SOV account for more than 87% of the world's languages. Properties Subject–verb–object languages almost always place relative clauses after the nouns which they modify and adverbial subordinators before the clause modified, with varieties of Chinese being notable exceptions. Although some subject–verb–object languages in West Africa, the best known being Ewe, use postpositions in noun phrases, the vast majority of them, such as English, have prepositions. Most subject–verb–object languages place genitives after the noun, but a significant minority, including the postpositional SVO languages of West Africa, the Hmong–Mien languages, some Sino-Tibetan languages, and European languages like Swedish, Danish, Lithuanian and Latvian have prenominal genitives (as would be expected in an SOV language). Non-European SVO languages usually have a strong tendency to place adjectives, demonstratives and numerals after the nouns that they modify, but Chinese, Vietnamese, Malaysian and Indonesian place numerals before nouns, as in English. Some linguists have come to view the numeral as the head in the relationship to fit the rigid right-branching of these languages. There is a strong tendency, as in English, for main verbs to be preceded by auxiliaries: I am thinking. He should reconsider. Sample sentences An example of SVO order in English is: Andy ate cereal. In an analytic language such as English, subject–verb–object order is relatively inflexible because it identifies which part of the sentence is the subject and which one is the object. ("The dog bit Andy" and "Andy bit the dog" mean two completely different things, while, in case of "Bit Andy the dog", it may be difficult to determine whether it's a complete sentence or a fragment, with "Andy the dog" the object and an omitted/implied subject.) The situation is more complex in languages that have no word order imposed by their grammar; Russian, Finnish, Ukrainian, and Hungarian have both the VO and OV constructs in their
