chondro-
IPA: PHONETIC RESPELLING:
作为构词元素意为“在。。。之下的；比。。少”（在化学中意为一个更低的化合价），来自希腊语的hypo（词性为介词和副词）“在…之下；up from under; toward and under (即 into)”，起源自PIE词根*upo“在…之下”
word-forming element in scientific compounds meaning "cartilage," from Latinized form of Greek khondros "cartilage" (of the breastbone), also "grain, grain of salt, seed, barley-grain," of uncertain origin. This is sometimes said to be from the PIE root meaning "to grind" which is the source of English grind (v.), but there are serious phonological objections and the word might be non-Indo-European [Beekes, "Etymological Dictionary of Greek"]. The body material so called for its gristly nature.
