Origin

From French terrifique, and its source, Latin terrificus (“terrifying”), from terrēre (“to frighten, terrify”) + -ficus, related to facere (“to make”). By surface analysis, terrify + -ic. The sense of excellent or amazing is an ameliorative semantic shift from the original sense of terrifying. Compare similar semantic development in sick and wicked.
