Ablative

In Latin, there are six cases: nominative, genitive, dative, accusative, ablative, and vocative.

The ablative plural of "rosa" is "rosis".

As Paul says, it is really perfectly gratuitous ("es ist im grunde reine willkur") to call the case we have in German (and Old English) a dative, for besides the functions of the dative it fulfils the functions of the old locative, ablative, and instrumental.

Different verbs can have objects in the accusative or a different case (e.g. the dative or the ablative).

Where the heart is forestalled with misopinion, ablative directions are found needful to unteach error, ere we can learn truth.

The inner layer of warship protection consists of ablative armor plate designed to "boil away" when heated. The vaporized armor material scatters a DEW beam, rendering it ineffectual.
