Spanish

A well-known DOM language is Spanish. In Spanish, direct objects that are both human and specific require a special marker (the preposition a "to"):^[6][7][8][9]

• Pedro besó a Lucía. = Peter kissed Lucy. (Literally, "Peter kissed to Lucy")

Inanimate direct objects do not usually allow this marker, even if they are specific:

• Pedro besó el retrato. = Peter kissed the picture.

Yet, some animate objects that are specific can optionally bear the marker:

• Pedro vio (a) la gata. = Peter saw (to) the cat-FEM

Some dialectal variation has been attested regarding the use of DOM in different varieties of Spanish. Balasch finds that, while the linguistic factors conditioning the use of DOM remain the same in both Mérida (Venezuela) Spanish and Madrid Spanish, DOM appears much more often in Madrid data.^[10] Furthermore, Tippets and Schwenter find that a factor known as relative animacy (the animacy of the direct object relative to that of the subject) is quite important in the implementation of DOM in varieties of Spanish such as Buenos Aires and Madrid Spanish. ^[11]

Sakha

In languages like Turkish, Kazakh and Sakha, more "prominent" objects take an overt accusative marker while nonspecific ones do not. Lack of an overt case marker can restrict an object's distribution in the sentence.^[12] Those orders are permitted in Sakha if accusative case is overtly expressed:

However, when the object is nonspecific, only the first (a) of the following sentences is grammatical, while alternative ordering as in the other three sentences (b-d) is not permitted (an asterisk * marks ungrammatical sentences):

When the direct object is low on the definiteness scale, it must directly precede the verb, whereas alternative ordering is possible when the direct object is higher in prominence.

Other languages

Other examples of languages with differential object marking are Persian, Turkish, Copala Triqui, Khasi, Tamil, Malayalam, Hindi, Marathi, Kham, Hebrew and Amharic. A number of languages in Mozambique also show differential object marking.^[13] In Turkish, the direct object can either have accusative case or have no (visible) case at all; when it has accusative case, it is interpreted as specific (e.g. one specific person), and otherwise it is interpreted as nonspecific (e.g. some person).^[14] Most modern Indo-Aryan languages like Hindi and Marathi also exhibit something similar, where direct objects must be explicitly marked as accusative in the case of definite or often animate participants.^{[15]: 3 [16]: 327–334} Due to the accusative and dative markers being identical for many Indo-Aryan languages, some analyses assert that the accusative case is always unmarked (like the nominative), and instead the dative markers are identical to those for differential object marking.^{[17]: 5–12}

Other DOM languages include some Aromanian dialects, precisely those of Krania, in Thessaly, Greece; and in the western dialects of Ohrid, in North Macedonia. Romanian also has DOM through the marker pe, these two and Spanish being the only Romance languages with this linguistic feature.^[18]

In addition to spoken languages, DOM is also found in some sign languages. In German Sign Language, for example, animate direct objects receive an additional marker while inanimate direct objects do not.^[5]
