Etymology

Origin of adrenal

1870–75; ad- + Latin rēn- (stem of rēnēs kidneys) + -al 1

Explanation

The adjective adrenal describes something near the kidneys. The adrenal glands control the release of stress hormones in the body. Adrenal is a scientific term describing a pair of endocrine glands that sit at the top of the kidneys in the human body. These glands control the way the kidneys work, as well as affecting stress hormones like adrenaline. The word adrenal, "of or near the kidneys," comes from Latin roots: ad-, "at or near," and renes, "kidneys."
