kernelyoudaoicibaDictYouDict[kernel 词源字典]
kernel: [OE] Etymologically, a kernel is a ‘little seed’. Old English corn, ancestor of modern English corn, meant ‘seed, grain’, and its diminutive form cyrnel was applied to ‘pips’ (now obsolete), to ‘seeds’ (a sense which now survives only in the context of cereals), and to the ‘inner part of nuts, fruit stones, etc’.

porridge: [16] Porridge is a 16th-century alteration of pottage [13]. This originally denoted a stew of vegetables and sometimes meat, boiled to submission, but it gradually came to be applied to a gruel, of varying consistency, made of cereals, pulses, etc, and it was the sort made from oatmeal that eventually took over the word porridge. Its transformation from pottage took place via an intermediate poddage (the t pronounced /d/ as in American English), and the change to r is mirrored in such forms as geraway and geroff for getaway and get off.

The same thing happened in the case of porringer ‘dish’ [16], which came from an earlier pottinger. Pottage itself was acquired from Old French potage, which etymologically meant simply ‘something from a pot’ (it was a derivative of pot ‘pot’). English reborrowed it in the 16th century as potage ‘soup’.

ChloeyoudaoicibaDictYouDict
fem. proper name, Latin, from Greek Khloe, literally "young green shoot;" related to khloros "greenish-yellow," from PIE *ghlo- variant of root *ghel- (2) "to shine," with derivatives referring to bright materials and gold, and bile or gall (such as Latin helvus "yellowish, bay," Gallo-Latin gilvus "light bay;" Lithuanian geltonas "yellow;" Old Church Slavonic zlutu, Polish żółty, Russian zeltyj "yellow;" Sanskrit harih "yellow, tawny yellow," hiranyam "gold;" Avestan zari "yellow") and "green" (such as Latin galbus "greenish-yellow;" Greek khloros "greenish-yellow color," kholos "bile;" Lithuanian zalias "green," zelvas "greenish;" Old Church Slavonic zelenu, Polish zielony, Russian zelenyj "green;" Old Irish glass, Welsh and Breton glas "green," also "gray, blue").

Buck says the interchange of words for yellow and green is "perhaps because they were applied to vegetation like grass, cereals, etc., which changed from green to yellow." It is possible that this whole group of yellow-green words is related to PIE root *ghlei- "to shine, glitter, glow, be warm" (see gleam (n.)).
