fǣr

Old English fǣr meant 'sudden danger,' 'calamity,' or 'peril.' It was an event, not a feeling. When the Anglo-Saxon Chronicle described a fǣr, it meant something terrible had happened — a raid, a disaster, a stroke of misfortune. The emotion you felt during a fǣr had no special name; the word described the world, not your reaction to it.

The shift from external event to internal state took centuries. In Middle English, fere and feer gradually migrated inward. By the 1300s, the word could mean either the danger or the feeling caused by it. By the 1400s, the feeling had won. Fear was now something you experienced, not something that happened. The Old Norse cognate fár, meaning 'harm' and 'distress,' reinforced both senses during the Viking period.

This shift — from world to mind — happened to other emotion words too. 'Worry' once meant 'to strangle.' 'Awful' meant 'full of awe.' But fear's migration is particularly clean. The same three letters went from naming a Viking raid to naming the flutter in your stomach before a job interview. No sound change, no borrowing, just a complete relocation from the external world to the internal one.

German kept the older meaning longer. Gefahr still means 'danger' in modern German — the external event, not the internal response. English and German split the word between subject and object, and each language chose a different side.
