409. MOBILE NOUNS have different forms to distinguish sex: as, #Iūlius#,
a man, _Julius_, #Iūlia#, a woman, _Julia_; #cervus#, _stag_, #cerva#,
_hind_; #socer#, _father-in-law_, #socrus#, _mother-in-law_; #victor#,
_conqueror_, #victrīx#, _conqueress_. Adjectives ‘of three endings’
(611), belong to this class.
410. Some nouns have one ending, but are applicable to either sex. Such
are said, to be of _Common Gender_: as, #adulēscēns#, _young man_ or
_young woman_; #dux#, _leader_; #īnfāns#, _baby_, _child_; and many
other consonant stems or stems in #-i-#, denoting persons. Adjectives
‘of two endings’ or ‘of one ending’ (611), belong to this class.
411. EPICENES have one ending and one grammatical gender, though
applicable to animals of either sex. Thus, #aquila#, _eagle_, is
feminine, though it may denote a _he-eagle_ as well as a _she-eagle_;
#anatēs#, _ducks_, feminine, includes _drakes_.
