With respect to speech, native speakers have consistently told me that if I "entender" them, I understand the words they are saying. If I "comprender" them, I actually understand the meaning, such as understanding an explanation of a task.
The example they gave me was, "Te entiendo pero no comprendo." Meaning, I understand the words you are saying, but I don't know what you mean by them.
IN the discussion groups we cannot see what you put that was marked wrong unless you include it in your message. If you tell us what you entered, then we can help!
:)) I think Paige did show her incorrect response, Bishop: "I didn't understand this."
Esto is what we use when the gender of what you're referring to is unclear. Este would be used if it were known to be masculine.
"I can't understand this." ?? (Not sure whether to report that my answer should be accepted.)
I answered with "I do not understand this" ........ and was told it was incorrect! Yo no comprendo esto. No son lo mismo?
