Numbers with gender: един, една, двама

The numbers one and two change with the noun.

• един (m), една (f), едно (n), едни (with plural-only and pair nouns such as очила, маратонки)
• два (m) and две (f, n): два билета, две сестри, две деца

For men or mixed groups of people Bulgarian uses personal numerals: двама, трима, четирима, петима: двама мъже, трима студенти. They also stand alone: Бяхме петима (There were five of us), Крадците бяха четирима (There were four thieves). They are never used with feminine or neuter nouns: три жени, три деца. From four up, пет студенти is also correct, so the higher ones are practised standing alone.
