Here are some examples of how you might use "entiendo" in Argentina:
* "Entiendo lo que estás diciendo." (I understand what you're saying.)
* "¿Entiendes el problema?" (Do you understand the problem?)
* "No entiendo." (I don't understand.)
It's important to note that in Argentina, just like in other Spanish-speaking regions, there can be slight variations in pronunciation and intonation, but the meaning of the word "entiendo" remains the same.
