A. NOUNS.

12. A Noun is the name of a _person_, _place_, _thing_, or _quality_; as,
Caesar, _Caesar_; Rōma, _Rome_; penna, _feather_; virtūs, _courage_.

1. Nouns are either Proper or Common. Proper nouns are permanent names of
persons or places; as, Caesar, Rōma. Other nouns are Common: as, penna,
virtūs.

a) Concrete nouns are those which designate individual objects; as, mōns,
_mountain_; pēs, _foot_; diēs, _day_; mēns, _mind_.

Under concrete nouns are included, also, collective nouns; as, legiō,
_legion_; comitātus, _retinue_.

b) Abstract nouns designate qualities; as, cōnstantia, _steadfastness_;
