spelt (n.)youdaoicibaDictYouDict[spelt 词源字典]
type of grain, Old English spelt "spelt, corn," perhaps an early borrowing from Late Latin spelta "spelt" (noted as a foreign word), which is perhaps from Germanic *spilt-, from PIE *speld-, extended form of root *spel- (1) "to split, to break off" (probably in reference to the splitting of its husks in threshing); see spill (v.).

The word had little currency in English, and its history is discontinuous. Widespread in Romanic languages (Italian spelta, Spanish espelta, Old French spelte, Modern French épeautre). The word also is widespread in Germanic (Old High German spelta, German Spelt), and a Germanic language is perhaps the source of the Late Latin word.[spelt etymology, spelt origin, 英语词源]
