Etymology
The term "fat-soluble" is derived from the English words "fat" and "soluble". "Fat" comes from the Old English "fætt", which means "stuffed, full, plump", and "soluble" comes from the Latin "solubilis", which means "that can be loosened or dissolved". The term "vitamin" was coined in 1912 by the Polish biochemist Casimir Funk to denote a vital substance in the diet.
