In the sixteenth class of the Latin from Scratch course, we’ll study the fifth declension, so we finish with declensions. There are not many nouns in the fifth declension and they are not so frequent except for a few of them. We’ll only find one type.

Morphology of the fifth declension
We already know that the nouns of the fifth declension are those in whose statement we can see that the genitive ends in ‑ei.
nom. sg. | diēs | nom. pl. | diēs |
voc. sg. | diēs | voc. pl. | diēs |
ac. sg. | diĕm | ac. pl. | diēs |
gen. sg. | diēī | gen. pl. | diērŭm |
dat. sg. | diēī | dat. pl. | diēbŭs |
ab. sg. | diē | ab. pl. | diēbŭs |
All the nouns are feminine. The only exception is dies, diei (and its compound meridies, meridiei), which is masculine with the wider meaning of ‘day (period of time)’ and feminine with the more specific meaning of ‘appointed day, date’.

There aren’t many nouns in the fifth declension. However, some of them are worth memorizing:
