mindmap root((ANTE)) antechamber An outer room that leads to another and is often used as a waiting room.
🌱The antechamber to the lawyer's office was both elegant and comfortable, designed to inspire trust and confidence. 🌳One expects to find an antechamber outside the private chambers of a Supreme Court Justice or leading into the great hall of a medieval castle. In the private end of the castle the lord's or lady's bedchamber would have its own antechamber, which served as a dressing room and sitting room, but could also house bodyguards if the castle came under siege. Anteroom is a less formal synonym, one that's often applied to the waiting rooms of professional offices today. antedate 1、 To date something （such as a check） with a date earlier than that of actual writing.
2、 To precede in time.
🌱Nantucket Island has hundreds of beautifully preserved houses that antedate the Civil War. 🌳Dinosaurs antedated the first human beings by almost 65 million years, though this stubborn fact never used to stop cartoonists and screenwriters from having the two species inhabit the same story line. Dictionary editors are constantly noticing how the oral use of a word may antedate its first appearance in print by a number of years. Antedating a check or a contract isn't illegal unless it's done for the purpose of fraud （the same is true of its opposite, postdating）. antecedent 1、 A word or phrase that is referred to by a pronoun that follows it.
2、 An event or cause coming before something.
🌱As I remember, she said "My uncle is taking my father, and he's staying overnight," but I'm not sure what the antecedent of "he" was. 🌳A basic principle of clear writing is to keep your antecedents clear. Pronouns are often used in order not to repeat a noun （so instead of saying "Sheila turns 22 tomorrow, and Sheila is having a party," we replace the second "Sheila" with "she"）. But sloppy writers sometimes leave their antecedents unclear （for instance, "Sheila helps Kathleen out, but she doesn't appreciate it," where it isn't clear who "she" is）. Watch out for this possible problem when using not just he and she but also they, them, it, this, and that. And keep in mind that antecedent isn't just a grammar term. You may talk about the antecedents of heart disease （such as bad eating habits）, the antecedents of World War II （such as the unwise Treaty of Versailles）, and even your own antecedents （your mother, grandfather, etc.）. anterior 1、 Located before or toward the front or head.
2、 Coming before in time or development.

Anatomy books refer to the anterior lobe of the brain, the anterior cerebral artery, the anterior facial vein, etc. Scholar and lawyers may use anterior to mean "earlier in time or order." For example, supporters of states' rights point out that the individual states enjoyed certain rights anterior to their joining the union. And prenuptial agreements are designed to protect the assets that one or both parties acquired anterior to the marriage.
