Ideogram (指事): A shield (十, contraction of 盾 and similar but unrelated to 中) and the radical of the mouth (口) both as a distinguishing mark and as a component that partly indicates pronunciation. Together, they indicate the concept of "strong, firm" (as strong as a shield); original form of 固 (OC *kaːs) (Qiu Xigui, Ding Shan 丁山). Later, the meaning of "solid, firm" shifted to "antiquity" for unclear reasons. Compare oracle bone forms with 干, 盾. Unrelated to 中 and hence to 史 and 使.

Fang (1982) finds evidence for the 十 component originally being a depiction of a piece of food and the character originally being a depiction of someone spitting out a piece of food due to his bad taste. Thus, Fang argues this character is the original form of 苦 (kǔ), "bitter".

Etymology

From Proto-Sino-Tibetan *r-ga (“old”). Cognate with 故 (OC *kaːs, “old things; former; dead”) and Tibetan རྒ (rga, “to be old; aged”).
