ablativform.

ablativ + form, first part from Latin (cāsus) ablātīvus (“ablative case, ablative”), from ablātus (“taken away, stolen, having been stolen”) (with the suffix -īvus, from Proto-Indo-European *-iHwós, from *-wós), perfect passive participle of auferō (“to take away”), from both ab- (“from, away, off”), from ab (“from, away from, of”), from Proto-Italic *ab, from Proto-Indo-European *h₂epó (“off, away”) + and from ferō (“to bear, carry, bring”), from Proto-Italic *ferō (“to carry, bear”), from Proto-Indo-European *bʰéreti (“to be carrying”), from *bʰer- (“to bear, carry”). Last part from Old Norse form, from Latin forma (“form; figure, shape, appearance”), from fōrma (“form, figure, shape, appearance”), perhaps from Etruscan *morma, from Ancient Greek μορφή (morphḗ, “shape, form, appearance”), possibly of Pre-Greek origin.
