Adam's appleyoudaoicibaDictgodict[Adam's apple 词源字典]
Adam's apple: [18] The original apple in question was the forbidden fruit of the tree of the knowledge of good and evil, which the serpent in the Garden of Eden tricked Eve into eating, and which she in turn persuaded Adam to eat. It was traditionally believed that a piece of it stuck in Adam’s throat, and so it became an appropriate and convenient metaphor for the thyroid cartilage of the larynx, which protrudes noticeably in men.

Adam's apple (n.)youdaoicibaDictgodict
1731, corresponding to Latin pomum Adami, perhaps an inexact translation of Hebrew tappuah haadam, literally "man's swelling," from ha-adam "the man" + tappuah "anything swollen." The reference is to the legend that a piece of the forbidden fruit (commonly believed to be an apple) that Eve gave Adam stuck in his throat. The term is mentioned in early 15c. as the name of an actual oriental and Mediterranean fruit, a variety of lime with an indentation fancied to resemble the marks of Adam's teeth.
