anguishyoudaoicibaDictYouDict[anguish 词源字典]
anguish: [13] English acquired anguish from Old French anguisse, changing its ending to -ish in the 14th century. Its central notion of ‘distress’ or ‘suffering’ goes back ultimately (as in the case of the related anger) to a set of words meaning ‘constriction’ (for the sense development, compare the phrase in dire straits, where strait originally meant ‘narrow’).

Old French anguisse came from Latin angustia ‘distress’, which was derived from the adjective angustus ‘narrow’. Like Greek ánkhein ‘squeeze, strangle’ (ultimate source of English angina [16]) and Latin angere ‘strangle’, this came originally from an Indo-European base *angg- ‘narrow’.

narrow: [OE] Narrow comes from a prehistoric Germanic *narwaz, whose only other modern representative is Dutch naar ‘unpleasant, sad’ (although it also occurs in Norva-sund, the Old Norse term for the ‘Straits of Gibraltar’). It is not known for certain where it comes from, but a connection has been suggested with Latin nervus ‘sinew, bowstring’ (source of English nerve) and Old High German snuor ‘string’, which might point back to an ancestral sense ‘tying together tightly’.
