“Faculty” has two main meanings in English, especially in education:

  1. In schools and universities
    • The group of teachers or academic staff at a school, college, or university. For example: “The science faculty are meeting today” or “She joined the faculty at Harvard.”
 * A division or group of related departments in a university, like “Faculty of Law” or “Faculty of Arts.”
  1. As an ability
    • A natural mental or physical ability, such as the “faculties” of sight, hearing, memory, or reasoning. For example: “He retained all his mental faculties” or “She has a faculty for learning languages.”

In short: in everyday academic talk, “faculty” usually means teachers or a big academic division; in a more general or formal sense, it means a natural ability or power of mind or body.
