Editing Romanian grammar (section)

===Number===
Romanian has two [[grammatical number]]s: singular and [[plural]]. Morphologically, the plural form is built by adding specific endings to the singular form. For example, nominative nouns without the definite article form the plural by adding one of the endings '''-i''', '''-uri''', '''-e''', or '''-le'''. The plural formation mechanism, often involving other changes in the word structure, is an intrinsic property of each noun and has to be learned together with it.

Examples:
* '''-i''': {{lang|ro|pom}} – {{lang|ro|pomi}} ('tree'), {{lang|ro|cal}} – {{lang|ro|cai}} ('horse'), {{lang|ro|tată}} – {{lang|ro|tați}} ('father'), {{Lang|ro|barcă}} – {{Lang|ro|bărci}} ('boat');
* '''-uri''': {{lang|ro|tren}} – {{lang|ro|trenuri}} ('train'), {{lang|ro|treabă}} – {{lang|ro|treburi}} ('job, task'), {{lang|ro|cort}} – {{Lang|ro|corturi}} ('tent');
* '''-e''': {{lang|ro|pai}} – {{lang|ro|paie}} ('straw'), {{lang|ro|masă}} – {{lang|ro|mese}} ('table, meal'), {{lang|ro|teatru}} – {{lang|ro|teatre}} ('theater'), {{lang|ro|muzeu}} – {{lang|ro|muzee}} ('museum');
* '''-le''': {{lang|ro|stea}} – {{lang|ro|stele}} ('star'), {{lang|ro|cafea}} – {{lang|ro|cafele}} ('coffee'), {{lang|ro|pijama}} – {{lang|ro|pijamale}} ('pajama').
