IPA: /təˈrɪfɪk/
KK: /tɛˈrɪfɪk/
Something that is extremely good or impressive; it can also mean something that causes fear or is very bad in certain contexts.
The concert was absolutely terrific, and everyone enjoyed it.
Comparative: more terrific
Superlative: most terrific
Terrific is formed from "terrere" (meaning to frighten) and the suffix "-ific" (meaning making or causing). Originally, it described something that causes terror or fright, but over time, it has evolved to mean something extraordinarily good or impressive.
Think of something that 'frightens' ('terrere') and 'makes' ('-ific') a strong impression — that's how terrific came to mean something amazing.
