An Oath Is a Solemn Promise or a Curse

An oath is a formal sworn statement. It is also a swear word, and the link is direct.

An oath is a solemn promise, often invoking something sacred, and also a profane exclamation. The two senses connect through the verb *swear*, which covers both: to swear an oath in court and to swear at someone are the same word, because profanity originally meant invoking sacred names improperly. That is why *by God* and *bloody* โ€” thought to be from *by our Lady* โ€” began as broken oaths rather than as obscenities. English *oath* is Old English *aรฐ*, shared across the Germanic languages.
