Fifth declension

Fifth declension is the smallest declension - not very many words are part of it. You can tell that a word is fifth declension if it has -ei in genitive singular.

Here are the endings for fifth declension:
​
Singular
Plural
Nominative
-es
-es
Genitive
-ei
-erum
Dative
-ei
-ebus
Accusative
-em
-es
Ablative
-e
-ebus
And here's an example of a fifth declension word declined. For some reason, only two words in fifth declension actually have all of their forms - dies, diei (day) and res, rei (thing/matter). Most fifth declension nouns don't have plural forms. Dies, diei is even more unusual because it is the only masculine word in fifth declension.
​
Singular
Plural
Nominative
dies
dies
Genitive
diei
dierum
Dative
diei
diebus
Accusative
diem
dies

diebus
Some fifth declension words, like series, -ei and species, -ei have pretty much come straight into English. They became the words series and species, respectively.
