The word anxiety derives from the Latin substantive angor and the corresponding verb ango (to constrict). A cognate word is angustus (narrow). These words derive from an Indo-European root that has produced Angst in modern German (and related words in Dutch, Danish, Norwegian, and Swedish). Interestingly, the same relationship between the idea of narrowness and anxiety is attested in Biblical Hebrew. In fact, Job expresses his anguish (Job 7:10) literally with the Hebrew expression “the narrowness (tsar) of my spirit.”
