Introduction

The fifth declension is a small group of feminine nouns.

There are no adjectives in the fifth declension.

The typical ending of a fifth declension noun is -i- in front of Nom.Sg. -es.

Some examples of fifth declension nouns are:

dies, ei f-day

dosis pro die (daily dose)

facies, ei f-face, surface

series, el f-series, row

superficies, ei f-surface

species, ei f-species, pl. t. -tea

One of the most common nouns in Latin, res (thing), is found in the fifth declension.

"Res" is where English gets the word "republic," which literally means "public thing" (res publica).
