I cannot find any source explaining the Latin names of grammatical cases. I am especially curious in the names of the less common cases, like in Finnish:
or like in Czech:
I can guess the meaning of some of them, such as nominative (name), partitive (part of a whole), accusative (to blame), dative (to give), instrumental (by means of, using something as an instrument).
By meaning I mean the meaning of the Latin words used in the grammar terminology and their connection with what each case expresses.
But is there any source in one single place with the explanation of the meaning of them all? Could we make this question to serve as such?
