kaolin
UK[ˈkeɪəlɪn]US[ˈkeɪəlɪn]
n
a fine, soft, white clay, used in making porcelain and china and in medicine.
Etymology
the word 'kaolin' entered the english language in the early 18th century from french. the french term was derived from 'kao-ling', the name of a mountain near jingdezhen in jiangxi province, china, which was a historic source of this fine white clay. the name literally means "high ridge" in chinese. thus, the term's journey is a direct example of a toponym becoming a globally recognized material name, moving from a specific geographical location to denote the essential substance for porcelain production.
Analysis
this word is a loanword from french, which itself borrowed it from a chinese toponym. it is not productively formed from classical morphemes within english and is therefore treated as unsegmentable.
Examples
the delicate vase was made from pure white kaolin.
kaolin is often used in skincare products for its absorbent properties.
the region's economy historically depended on mining kaolin for the pottery industry.
