KK: /fɪˈlɪpɪk/
A speech or piece of writing that strongly criticizes someone or something, often in a bitter way.
The senator delivered a philippic against the proposed law, expressing his strong disapproval.
Philippic → It is derived from the Greek word "Philippikos" (meaning of or relating to Philip), specifically referring to the speeches made by Demosthenes against Philip II of Macedon. The term has come to mean a bitter attack or denunciation, particularly in a speech or writing.
Think of the speeches against Philip, which were strong and critical, to remember that a 'philippic' is a fierce verbal attack.
