13. There are three Genders,--Masculine, Feminine, and Neuter. Gender in
Latin is either natural or grammatical.

Natural Gender.

14. The gender of nouns is natural when it is based upon sex. Natural
gender is confined entirely to names of persons; and these are--

1. Masculine, if they denote males; as,--

nauta, _sailor_; agricola, _farmer_.

2. Feminine, if they denote females; as,--

māter, _mother_; rēgīna, _queen_.

Grammatical Gender.

15. Grammatical gender is determined not by sex, but by the general
signification of the word, or the ending of its Nominative Singular. By
grammatical gender, nouns denoting things or qualities are often Masculine
or Feminine, simply by virtue of their signification or the ending of the
Nominative Singular. The following are the general principles for
determining grammatical gender:--

_A. Gender determined by Signification._

1. Names of _Rivers_, _Winds_, and _Months_ are Masculine; as,--

Sēquana, _Seine_; Eurus, _east wind_; Aprīlis, _April_.
