PARA vs. POR
As with SER vs. ESTAR, PARA and POR might become more subtle and sophisticated with your degree of expertise in SPANISH. Yet, here is a very concise and useful explanation of them for your convenience…
PARA= DESTINO
POR= ORÍGEN GENERADOR
===================
Did you KNOW that when you DECLARE A DESTINATION, PARA , is the preposition to use?
For instance: a)..La sopa es PARA tí (The soup is for you): “You” is a DESTINATION. A destination requires PARA ;)
b)..Voy PARA mi casa (I’m going to my house): A destination requires PARA.
===================
P O R shows ORíGEN GENERADOR (who made it?);
For instance: a)…La sopa está hecha por Gloria… (both: origen OR generation -Soup was made by Gloria… (the person who created the soup, originated it ;)
b)…El libro fué escrito POR García Márquez...The book was written BY García Márquez (García Márquez originated the book…)
