I thought this community might enjoy this character origin. To me, it really empasizes the Chinese cultural understanding of dialectics (although dialectics is 辩证法). This morpheme really shines in the word 文化 (culture), emphasizing the cycle of life and death’s infuence on culture. This morpheme is used in words like 化学 (chemistry), 化妆 (to apply makeup), and 化石 (fossil). This etymology is from the Outlier Dictionary of Chinese Characters on Pleco, all credit to them. I highly recommend it as a resource for anyone interested. I can do more posts like this if the community is receptive to it. There are many, many fascinating 汉字. 大家加油!
yes, 儿化 means “er-ification”!
