444. Greek appellatives always take a Latin form in the dative singular
and in the plural, and usually throughout: thus, #poēta#, M., _poet_,
and #aula#, F., _court_, are declined like #mēnsa#. Masculines have
sometimes a nominative #-ēs# and accusative #-ēn#: as, #anagnōstēs#,
_reader_, #anagnōstēn#; rarely an ablative #-ē#: as, #sophistē#,
_sophist_. Greek feminines in #-ē# sometimes have Greek forms in late
writers: as, N. #grammaticē#, _philology_, G. #grammaticēs#, Ac.
#grammaticēn#, Ab. #grammaticē# (Quintil.).
445. Greek proper names sometimes have the following forms. Nominative
masculine #-ās#, #-ēs#: as, #Prūsiās#, #Atrīdēs#; feminine #-ā#: as,
#Gelā#, #Phaedrā#; #-ē#: as, #Circē#. Genitive feminine #-ēs#: as,
#Circēs#. Accusative masculine #-ān#, #-dēn#: as, #Aenēān#, #Pēlīdēn#;
feminine #-ēn#: as, #Circēn#. Ablative feminine #-ē#: as, #Tīsiphonē#.
Vocative #-ā# or #-a#: as, #Atrīdā#, #Atrīda#, #Thyesta#; #-tē#: as,
#Boōtē#; #-dē#: as, #Aeacidē#.
