In depth
Origin and naming
A standard label in modern linguistics: Andrew Sihler's Language History (2000) names the mistake of reading a word's past into its present, and Kenneth Wilson's Columbia Guide to Standard American English (1993) catalogues it among usage errors. It presumes words are answers to their roots, when they are answers to their users.
More places it shows up
In a comment thread, someone corrects the journalist: 'Decimate originally meant to kill one in ten, so using it for a 40% staff cut is just wrong.'
A style guide bans 'fulsome praise' because fulsome 'really means' excessive and insincere, though the writer meant what every current reader reads.
In a language forum, a user insists 'hysteria' can only ever refer to the uterine condition it was coined for, and any other use is 'illiterate'.
During the rebrand meeting, someone objects that 'awful' once meant 'full of awe', so the new slogan 'awfully good coffee' contradicts itself.
How to spot it
- The correction reaches for a dictionary's history column and skips the usage column.
- The argument would hold at any point in history, which is another way of saying it holds at none.
- Notice the pivot from 'used to mean' to 'really means' with no bridge in between.
