"Damn" is a "curse" word?
I imagine you are being sarcastic...
But, just in case:
The full meaning of the word is a request made to the Almighty that, whatever entity is named following the word (or a spoken or silent "it", while retaining the identity of the "it" in your mind) be
damned to an eternity in Hell.
I try not to use it, or any name of a holy Person or thing (and yes, Hell is holy).
Mere vulgarity, ancient English superseded by civilized French after 1066, is fair game to me though I limit its use in polite company lest I be mistaken for a
shit-head.
