1. What's the difference between "terrified" and "horrified"
2. Are "terrified" and "horrified" related to "terrible" and "horrible" in any way?
3. When I previously looked up the difference between "terrible" and "horrible," it seemed to suggest that "terrible" is less severe than "horrible." Based on that, can I simply understand that being "terrified" involves a less intense level of fright compared to being "horrified"?
Thank you so much！❤️

Answer

Terrified means extremely frightened.
Horrified combines feelings of being extremely frightened and extremely shocked. It could also just mean extremely shocked without any fear.

Terrible and horrible relate more to being extremely bad or shocking, rather than frightening, so the various forms of adjectives do not always relate to each other very exactly.

Answer

They have similar meanings. But terrified is more about being scared & traumatised, from a threat to your safety. Horrified is more about being shocked at something sickly/disgusting. So I would say I'm terrified by the man who wants to kill me, but I'm horrified at what he did last year to someone else.
