Origins
The word 'angst' is a German and Danish loanword that entered English freighted with existentialist philosophy.βββββββββββββββββββββββββββββββββββββββββββββββββββββββββββββββ In its source languages, 'Angst' (German) and 'angst' (Danish) are ordinary, everyday words meaning 'fear' or 'anxiety' β a German child afraid of the dark feels 'Angst,' with no philosophical implications. But the word's journey into English was mediated by two of the most influential philosophers of the nineteenth and twentieth centuries, and it arrived carrying their intellectual baggage.
The etymological root is ancient. German 'Angst' descends from Old High German 'angust' (narrowness, distress, anxiety), from Proto-Germanic *angustiz (tightness, narrowness, anguish), from PIE *hβenΗ΅Κ°- (tight, narrow, constricted, painful). This root is one of the most emotionally productive in the Indo-European family, generating words for different flavors of the same bodily sensation β constriction. Through Latin 'angere' (to choke, to squeeze), it produced English 'anxiety' (from 'anxius,' troubled β literally squeezed), 'anguish' (from 'angustia,' narrowness), and 'angina' (chest constriction). Through Old Norse 'angr' (grief, distress), it produced English 'anger.' Through German 'eng' (narrow, tight), it preserves the root's original spatial meaning. All these words describe the same physical experience β tightness in the chest, constriction of the throat, a feeling of being squeezed β but each names a different emotional interpretation of that sensation.
The philosophical career of 'Angst' began with Soren Kierkegaard's 1844 treatise 'Begrebet Angest' (The Concept of Anxiety), written in Danish. Kierkegaard distinguished between 'frygt' (fear of a specific, identifiable threat) and 'angest' (a deeper, objectless dread). His famous metaphor described angst as the 'dizziness of freedom' β the vertigo a person feels when standing at the edge of a cliff, not because they fear falling, but because they realize they are free to jump. Angst, for Kierkegaard, was the emotional response to confronting the terrifying openness of human possibility.
