Etymological fallacy

Etymology means the study of the history and origin of words. The etymological fallacy is when someone assumes that the original or historical meaning of a word is the only correct or true meaning of the word.

For example, let's say someone says, "The word 'nice' originally meant 'silly' or 'foolish,' so when someone says 'that's nice,' it actually means 'that's silly'." This is an example of the etymological fallacy because the current meaning of the word 'nice' is different from its original meaning.

It's important to remember that the meaning of words can change over time, and the current usage of a word is what matters most. The etymology of a word can be interesting and informative, but it's not always relevant to its current meaning.
