Origin of ablateBack-formation from ablation
(third-person singular simple present ablates, present participle ablating, simple past and past participle ablated)
From Latin ablatum past participle of auferre (“to remove”); au- (“away”) + ferre (“to carry”). First attested in the 1500s, it became obsolete by the early 1600s. Came back into use as a back-formation from ablation.
