difference between horror and terror

• It's the same thing. A few years ago horror books were usually called terror, but for marketing reasons, they are now usually called Horror. If you look at Amazon , they call their horror section- huh, horror section. I think maybe it has to do with the association of the word terror to other things, like terrorism. The same thing happens with movies. In the good old days, they were terror movies, not they're horror movies.

• I think terror is more realistic like when there is an earthquake or something, and horror is kind of more disturbing or more psychological. I don't know the real answer but that's what I think :)

• Horror: intense(үлэмж их, хүчтэй) and profound(маш гүнзгий) fear. 
  Terror: panic, an overwhelming(хэмжээлшгүй) feeling of fear and anxiety.

• Horror suggests an element of revulsion that needn't be present in terror. Horror could be showing somebody being murdered with a chain saw. Terror would be somebody anticipating(зөгнөх, совин татах) being murdered by a chain saw.
