* What's considered "bad" is subjective: What's offensive in one culture or time period might not be in another.
* Words evolve: Words can change meaning over time. A word that was once considered offensive might become neutral or even positive.
* Context matters: The same word can be offensive in one context and perfectly acceptable in another.
* There's no official list: There isn't a universally recognized list of bad words.
Rather than focusing on a number, it's more important to be aware of the potential impact of your language and to be respectful of others.
