Etymological fallacy

Abuse of the etymology of words.

The etymological fallacy is a genetic fallacy that argues for or against an idea or argument because of the etymological origin of the words, in an anachronistic way

Example:

“Logos” in ancient Greek meant “Word”

therefore “logic” has no other value than that of being a technique for manipulating words

Note: the example is a summary of the one developed in Fallacy Files
