Today I looked for the word desapercibido in the RAE and found the following:
desapercibido, da.
- adj. No apercibido.
Now, I know what desapercibido means, but then I was curious about the exact meaning of apercibido. So I looked for apercibido in the RAE and guess what:
Aviso
La palabra apercibido no está en el Diccionario.
All this came from a site that said that saying desapercibido for something that is inconspicuous was incorrect and that inadvertido should be used!!
Very confusing. Does someone have the exact meaning of apercibido? Since the RAE doesn't provide one.
