Definition & Meaning of "skinflint"in English

What is the origin of the term "skinflint" and how is it used?

"Skinflint" is a slang term used to describe a person who is miserly, stingy, or excessively unwilling to spend money. It likely emerged in English in the 17th century, combining "skin" (suggesting the thinnest, most minimal covering) with "flint" (a hard stone that sparks fire but gives little warmth), metaphorically portraying someone who is tight with money or resources. The term is derogatory but often used in informal, humorous, or social contexts to criticize frugality or greed. It is mildly offensive, more mocking than harshly insulting.
