Origin of angstGer: see anger

Origin of angstGerman, from Middle High German angest, from Old High German angust; see angh- in Indo-European roots.
(third-person singular simple present angsts, present participle angsting, simple past and past participle angsted)
- (informal) To suffer angst; to fret.
From the German word Angst or the Danish word angst; attested since the 19th century in English translations of the works of Freud and Søren Kierkegaard. (George Eliot used the phrase complete with definite article: "die Angst".) Initially capitalized (as in German), the term first began to be written with a lowercase "a" around 1940–44. The German and Danish terms both derive from Middle High German angest, from Old High German angust, from Proto-Germanic *angustiz; Dutch angst is cognate.
