All of these words are approximately the same. You can use them interchangeably. But, most people use "terrible", "horrible", or "awful" more often than "horrid" or "dreadful", which sound a little old-fashioned.

all the words have the same meaning. You can use them according to your mood.

terrible = extremely bad or serious. horrible = causing or likely to cause horror; shocking and very unpleasant. dreadful = used to emphasize the degree to which something is the case, especially something regarded with sadness or disapproval.

Where must be difference, a subtle nuance in meaning. for me it seems like this: awful- it's bad, end i can only be sorry for it. horrible- full of blood, killing facts terrible- it is pressing me in some way. dreadful- very bad looking. But i'm not sure/ Quote by Stephen King: But if I find that I cannot terrify, I will try to horrify,
