what is the contrary word for the word aprender
"Ignorar" is in spanish the antonym accepted
but in RAE (Spanis Royal Academy) dictionary the traduction of "desaprender" (opposite of aprender) is: Olvidar lo que se había aprendido.
the prefix "des" means opposite to something."Desaprender" is very good option.
If you want the english for "aprender" it means "to learn"
I assume the opposite therefore would be "enseñar" meaning "to teach"
Hope this Helps
'olvidar' could also be considered "the opposite".
Are you asking for an antonym (word with the opposite meaning)? If so, you could simply say:
Él no entiende italiano.
He does not understand Italian.
