Ablative (Latin)

In Latin grammar, the ablative case (cāsus ablātīvus) is one of the six cases of nouns. Traditionally, it is the sixth case (cāsus sextus, cāsus latīnus). It has forms and functions derived from the Proto-Indo-European ablative, instrumental, and locative. It expresses concepts similar to those of the English prepositions from; with, by; and in, at.^[1] It is sometimes called the adverbial case, since phrases in the ablative can be translated as adverbs: incrēdibilī celeritāte, 'with incredible speed', or 'very quickly'.
