What is a swearword in linguistics?

A swear Word is any proscribed Word according to moral and religious law, but sometimes according to civil law. Swear Words are usually interjections but can be used in any part of speech to emphasize what one is saying or to insult or threaten someone most often in anger. Because they are used most often in anger, swear Words are usually verbal substitutes for physical aggression. Swear Words are usually used in reference to religion, whether they refer to the names of deities, angels, or saints. Swear Words can also be used in reference to the functions and parts of the living body, usually in reference to excretion and sexual intercourse. Although they shouldn't be used, swear Words are common in speech although more rare in writing. Swear Words are commonly put in a separate category of prohibited Words along with those in reference to race, ethnicity, and sexual orientation.
