Referring to Vincent’s video:

[4] 4th declension

Here are the group links to posts on the 4th and 5th declension

Nominative: arcus pluvius > accusative: Arcum pluvium in caelō videō. │ I see a rainbow in the sky.

Nominative: tonitrus > accusative: Tonitrum in caelō audiō. │ I hear thunder in the sky.

Nominative plural: Duo arcūs pluviī in caelō sunt. │ There are two rainbows in the sky.

> Accusative plural: Duōs arcūs pluviōs in caelō videō. │ I see two rainbows in the sky.

What this topic also shows is that Latin nouns can have the same ending but belong to different declensions:

2nd declension: corvus (crow)

3rd declension: sidus (star; constellation)

4th declension: tonitrus (thunder)

Level 1: learn the meanings of the word

Moving on …

There is no way of knowing what declension they belong to if you only know the nominative of the word. However, all the genitive singular forms of the nouns are different which is why, when thoroughly learning Latin nouns, you need to know both the nominative and genitive singular because that will give you the declension; dictionaries and textbooks will always list the nouns that way. That is particularly crucial with 3rd declension nouns because they often undergo a change in the genitive singular which applies to all endings added to the word:

2nd declension

corvus [nominative singular], corvī [genitive singular]; abbreviated to corvus, -ī [2/m]

3rd declension

sidus, sideris [3/n] > Siderin caelō videō.

4th declension

tonitrus, tonitrūs; abbreviated to tonitrus, -ūs [4/m]
