Almost from the start, just horrid (5)

I believe the answer is:
awful
'horrid' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for awful that I've seen before include "shocking" , "Exceptionally bad" , "Not good at all" , "Dreadful, nasty" , "gruesome!" .)
