The Fifth declension nouns in Latin are sometimes called -e stem nouns. The nouns are few but common. Like the first declension, fifth declension nouns tend to be feminine. The forms are easily mistaken for 3d declension forms. Mistaking an accusative plural fifth declension noun for an accusative plural third declension noun, for instance, as long as you have the gender right, should cause no trouble in translation.
