cortisol (n.)

"steroid hormone found in the adrenal cortex," manufactured synthetically as an anti-inflammatory, 1949, coined by its discoverer, Dr. Edward C. Kendall, from a shortening of its chemical name, 17-hydroxy-11 dehydrocorticosterone, which is ultimately from Latin corticis (genitive of cortex; see cortical) and so called because it was obtained from the "external covering" of adrenal glands. Originally called Compound E (1936).

word-forming element in chemistry, variously representing alcohol, phenol, or in some cases Latin oleum "oil" (see oil (n.)).
