Appendix:Romanian nouns/Masculine

Masculine nouns are the easiest to decline in Romanian, as there is very little irregularity. The plurals of all masculine nouns (even those with irregular plurals, such as om (oameni)) end in -i.

Masculine nouns are generally not difficult to identify. They usually end in consonants, -u, -e or -i. Because neuter nouns can also end in all of these, they can sometimes take a bit of work to differentiate, however, masculine and neuter nouns generally end in different consonants.

Masculine nouns ending in consonants will generally end in:

• r (-or, -tor, -ar, -er)
• c (-ic),
• t (-ist),
• n (-an, -ean, -ân) or
• z (-ez)

Neuter nouns ending in consonants will usually end in:

• m (-ism),
• t (-ment, -mânt, -ut) or
• j (-aj)
