In German, words that take completely different meanings when used with different articles are called "false friends." Examples of such words include: "der Bank" (meaning "the bank" as in a financial institution) vs. "das Bank" (meaning "the bench") "der Rat" (meaning "the council" or "the advice") vs. "das Rat" (meaning "the rat") "der Arm" (meaning "the arm" as in a body part) vs. "das Arm" (meaning "poverty" or "the poor") "der Bass" (meaning "the bass" as in a low-pitched voice or instrument) vs. "das Bass" (meaning "the bass" as in a type of fish) It's important to pay attention to the articles when using such words, as they can completely change the meaning of the word.
