There are several words in the German language that can have completely different meanings when used with different articles. Some examples include:

- "Bank" (without an article) typically refers to a financial institution, while "die Bank" refers to a bench or seating.
- "Baum" (without an article) typically refers to a tree, while "der Baum" refers to a specific tree.
- "Hand" (without an article) typically refers to a body part, while "die Hand" refers to a hand as in a hand gesture or a physical hand that allows us to pick things up.
- "Buch" (without an article) typically refers to a book, while "das Buch" refers to only one particular book. 

These examples highlight the importance of the use of articles in the German language, as they greatly influence the meaning of a word.
