vocative case cannot be determined by an indefinite article. Examples of indefinite article usage: Masculine: nominative/accusative: singular un copil (a child) – plural niște copii ([some] children); genitive/dative: singular unui copil (of/to a child) – plural unor copii (of/to [some] children); Neuter: nominative/accusative: singular un loc (a place) – plural niște locuri ([some] places); genitive/dative: singular unui loc (of/to a place) – plural unor locuri (of/to [some] places); Feminine: nominative/accusative: singular o masă (a table) – plural niște mese ([some] tables); genitive/dative: singular unei mese (of/to a table) – plural unor mese (of/to [some] tables); Article appended to adjectives When a noun is determined by an adjective, the normal word order is noun + adjective, and the article (definite or indefinite) is appended to the noun. However, the word order adjective + noun is also possible, mostly used for emphasis on the adjective. Then, the article and the case marker, if any, are applied to the adjective instead: Noun + adjective (normal order): un student bun (a good student); studentul bun (the good student); unui student bun (to a good student); studentului bun (to the good student). Adjective + noun (reversed order): un bun student (a good student); bunul student (the good student); unui bun student (to a good student); bunului student (to the good student). Demonstrative article The demonstrative article is used to put emphasis on the relative superlative of adjectives. The forms are cel and celui (m. sg.), cea and celei (f. sg.), cei and celor (m. pl.) and cele and celor (f. pl.). Genitival article There are situations in Romanian when the noun in the genitive requires the presence of the so-called genitival (or possessive) article (see for example the section "Genitive" in "Romanian nouns"), somewhat similar to the English preposition of, for example in a map of China. In Romanian this becomes o hartă a Chinei, where "a" is the genitival article. The table below shows how the genitival articles depend on gender and number. The genitival article also has genitive/dative forms, which are used only with a possessive pronoun. They are: alui (m. sg.), alei (f. sg.), and alor (pl., both genders). These forms are rarely used—especially the singular ones—and the sentences are usually rephrased to avoid them. Adjectives Romanian adjectives determine the quality of things. They can only fulfill the syntactical functions of attribute and of adjectival complement, which in Romanian is called nume
