I am hijacking this thread to express my general displeasure at popular use of the word claustrophobic. "The room is very claustrophobic"?? Really? How else does the wainscoting feel today?
>From Latin claustrum (“a shut-in place”), from claudō (“I shut, close; I imprison, confine”) + -phobia. First attested in the British Medical Journal
So it's not a corruption. It's a neologism.
