smile 词源(Etymology) - 趣词词源[英文版]

smile [smile 词源字典]: smile: [13] The Old English word for ‘smile’ was smearcian, ancestor of modern English smirk. This was descended ultimately from the Indo- European base *smei-, which also produced Greek meidos ‘laugh’, Sanskrit smeras ‘smiling’, Latvian smaidīt ‘smile’, and Russian smejat’ sja ‘laugh’. Smile, which from the 13th century began to push smirk towards the more specialized sense ‘smile in a self-satisfied way’, comes from the same base, and was probably borrowed from a Scandinavian source (Swedish has smila and Danish smile).
