When should the personal "a" be used in a sentence and why? provide an example of such.

 In Spanish, when the direct object is a person, it is preceded by the preposition "a."
Jorge llama a María. 
Jorge calls María. 

From the perspective of the English speaker, the personal "a" appears to be an extra word. From the perspective of the Spanish speaker, the personal "a" is required, and to not use it is a serious error.
