ELI5: Why do both "terrible" and "horrible" mean something bad, but "terrific" and "horrific" have two completely different meanings?

Originally, "terrific" meant something bad--it has the same Latin root as "terrible." Only in the late 19th century did it start to become colloquially used as a good word--the same way that something "awesome" is nowadays not awe-inspiring, but very good, or that being "sick" is a good thing to be.
