What is the difference between a curse, a cuss and a swear?

where you come from… In NY it’s a curse.

probably what trudacia said. Although I vary between saying all three.

Curse: a “spell” that witches, wizards, and mages etc. can cast upon you.
Cuss: that crazy old guy who lives on the corner and creeps people out.
Swear: a promise with penalty of death.

or, they’re all naughty words and a plague would be upon you if you uttered any of the words classified as a “curse,” “cuss,” or “swear.”

It depends, but my intuition says “Nothing.”

Per Merriam Webster:

Curse: A prayer or invocation for harm or injury to come upon one
Cuss: Alteration of curse
Swear: To take an oath is the primary meaning; to use profane or obscene language

There just different words for the same thing.

Personally I prefer swearing…..you don’t have to wish injury upon somone, it’s just got to be a very colourful expression…
