Does the word "curse" refers to a "swear word"? Or a "dark sorcery"?

You can think of a "curse" as being a type of evil spell wishing misfortune upon somebody. In this case, it is definitely not referring to a swear word and is closer in meaning to the "dark sorcery" that you mentioned in your question. Ex: Sleeping Beauty had a curse put on her by an evil witch. Ex: This house is cursed! Bad things happen to everyone that lives here.
