基

Characters in the same phonetic series (其) (Zhengzhang, 2003)

核

Phono-semantic compound (形聲 /形声, OC *ɡuːd, *ɡrɯːɡ): semantic 木 (“tree”) + phonetic 亥 (OC *ɡɯːʔ) – a kind of tree. Modern meanings are borrowed.
The definitions related to “to examine” come from the “kernel” sense, i.e. “to go to the core” (Schuessler, 2007).
Generally thought to be of Sino-Tibetan origin. It has been compared to Tibetan རག་ཙེ (rag tse), Karbi rak (Gong, 2002; Schuessler, 2007). However, Hill (2012) rejects the connection to the Tibetan word because most words ending with ཙེ (tse) are loanwords from Chinese words ending with the 子 suffix.
Smith (2011) groups this word with the following terms into a word family meaning “root, germ, generative core”:
* 荄 (OC *kɯː, “grassroot”) and its derivative 根 (OC *kɯːn, “root”),
* 骸 (OC *ɡrɯː, “(human) bones”) (also noted by Schuessler, 2007),
* 孩 (OC *ɡɯː, “child”),
* 亥 (OC *ɡɯːʔ, “sprouting stage”), i.e. "the moon’s first appearance" > "twelfth earthly branch".

Han compound

(mathematics, algebra, linear algebra) kernel


次

Characters in the same phonetic series (次) (Zhengzhang, 2003)
Ideogrammic compound (會意 /会意) and possibly phono-semantic compound (形聲 /形声, OC *sn̥ʰis): phonetic 二 (OC *njis, “two”) + semantic 欠. Given that the right part of the character depicts a man kneeling with an open mouth, the number two perhaps indicates "two people speaking".
As an alternative, the two horizontal traits 二 are the representation of some saliva spitted while speaking; hence, the act of speaking is represented without a reference to blown air or breathing (e.g., 曰, 丂, 于, 只). The original meaning was "to consult", 咨. Perhaps related to 㳄, which means "saliva"; however, this is not the original version of the character, but a variant.
Given that the character started meaning "following; inferior (to)", the component 二 in this second translation adds part of the meaning if interpreted as a number.
In all cases, the Kangxi radical "Ice" is a false friend of either "Number two" or two drops representing saliva; however, in some fonts, it is still possible to see 二. An old variant of the character is 𣄭.
Probably from *s- + 二 (OC *njis, “two”), from Proto-Sino-Tibetan *g/s-ni-s (Pulleyblank, 1962; Sagart and Baxter, 2012; STEDT).
