Editing Latin declension (section)

====Consonant stems====
The stem of a consonant-stem noun may be found from the genitive case by removing the ending ''-is''. For example, the stem of {{wikt-lang|la|pax|pāx, pācis}} {{abbr|f.|feminine}} 'peace' is ''pāc-,'' the stem of {{wikt-lang|la|flumen|flūmen, flūminis}} {{abbr|n.|neuter}} 'river' is ''flūmin-'', and the stem of {{wikt-lang|la|flos|flōs, flōris}} {{abbr|m.|masculine}} 'flower' is ''flōr-.''

Masculine, feminine and neuter nouns often have their own special nominative singular endings. For instance, many masculine nouns end in ''-or'' ({{wikt-lang|la|amor|amor, amōris}}, 'love'). Many feminine nouns end in ''-īx'' ({{wikt-lang|la|phoenix|phoenīx, phoenīcis}}, 'phoenix'), and many neuter nouns end in ''-us'' with an ''r'' stem in the oblique cases ({{wikt-lang|la|onus|onus, oneris}} 'burden'; {{wikt-lang|la|tempus|tempus, temporis}} 'time').

The locative endings for the third declension are ''-ī'' or ''-e'' (singular) and ''-ibus'' (plural), as in {{wikt-lang|la|rus|rūrī}} 'in the country' and {{wikt-lang|la|Tralles|Trallibus}} 'at Tralles'.<ref>Allen and Greenough. §80.</ref>
