Definition & meaning

ausklammern is a separable German verb with two main meanings:

  1. To exclude, leave out, or disregard something

    • It means deliberately not including something in a discussion, decision, calculation, or consideration.
    • Example: Dieses Problem wurde bei der Untersuchung ausgeklammert.
      “This problem was excluded from the investigation.”
  2. In mathematics: to factor out

    • It means removing a common factor from several terms and placing it outside parentheses.
