Before entering fully into the definition of the term ablative, it is essential that we proceed to determine the etymological origin of the word. In this sense, we have to say that it derives from Latin, in particular, from “ablativus”, which can be translated as “relative to what is carried” and that is the result of the sum of the following components:
-The prefix "ab-", which indicates separation.
-The word "latus", which derives from a verb that means "produce" or "carry."
-The "-tive" suffix, which is used to mention a passive or active relationship.

The idea of ablative It is used in the field of grammar and is linked to the construction of prayers .

Other example ablative case is "He died of an infection" (the preposition "by" allows to include the cause of death in the sentence in question).
