Errors in oral and written speech are found in the meaning of words or phrases, in spelling and syntax.

Based on this observation, we have attempted to present the correct or incorrect use of our language, avoiding time-consuming and tedious analyses. Our readers can easily and quickly identify their own mistakes, among other things.

Without linguistic biases or other prejudices, we have alphabetically organized our material, with explanatory additions where and when necessary. We believe that basic respect for our mother tongue requires serious study and proper use of it, otherwise we may irreparably expose ourselves in our writing or speech.
