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 oranges." 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.[1] The label SVO often includes ergative languages although they do not have nominative subjects.
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[2] (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.[3]
There is a strong tendency, as in English, for main verbs to be preceded by auxiliaries: I am thinking. He should reconsider.
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 is 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 strict order of V and O imposed by their grammar. e.g. Russian, Finnish, Ukrainian, or Hungarian. Here, the ordering is rather governed by emphasis.
Russian allows the use of subject, verb, and object in any order and "shuffles" parts to bring up a slightly different contextual meaning each time. E.g. "любит она его" (loves she him) may be used to point out "she acts this way because she LOVES him", or "его она любит" (him she loves) is used in the context "if you pay attention, you'll see that HE is the one she truly loves", or "его любит она" (him loves she) may appear along the lines "I agree that cat is a disaster, but since my wife adores it and I adore her...". Regardless of order, it is clear that "его" is the object because it is in the accusative case.
In Polish, SVO order is basic in an affirmative sentence, and a different order is used to either emphasize some part of it or to adapt it to a broader context logic. For example, Polish: "''Roweru'' ci nie kupię"|italic=unset (I won't buy you a bicycle), Polish: "''Od piątej'' czekam"|italic=unset (I've been waiting since five).[4]
In Turkish, it is normal to use SOV, but SVO may be used sometimes to emphasize the verb. For example, "John terk etti Mary'yi" (Lit. John/left/Mary: John left Mary) is the answer to the question "What did John do with Mary?" instead of the regular [SOV] sentence "John Mary'yi terk etti" (Lit. John/Mary/left).
German, Dutch, and Kashmiri display the order subject-verb-object in some, especially main clauses, but really are verb-second languages, not SVO languages in the sense of a word order type.[5] They have SOV in subordinate clauses, as given in Example 1 below. Example 2 shows the effect of verb second order: the first element in the clause that comes before the V need not be the subject. In Kashmiri, the word order in embedded clauses is conditioned by the category of the subordinating conjunction, as in Example 3.
If the embedded clause is introduced by the transparent conjunction zyi the SOV order changes to SVO. "mye ees phyikyir (zyi) tsi maa dyikh temyis ciThy".[6]
English developed from such a reordering language and still bears traces of this word order, for example in locative inversion ("In the garden sat a cat.") and some clauses beginning with negative expressions: "only" ("Only then do we find X."), "not only" ("Not only did he storm away but also slammed the door."), "under no circumstances" ("under no circumstances are the students allowed to use a mobile phone"), "never" ("Never have I done that."), "on no account" and the like. In such cases, do-support is sometimes required, depending on the construction.
