В чем разница между de el и del ?Пожалуйста, приведите примеры.

Concept:
«De» is a preposition, "of her"
«El» it is a definite article, "The child".

Before telling you the difference, look at the example
EXAMPLE
"Viste la foto de el parque natural"? --- NOT USE a "long" and less appropriate way
-The preposition "de", followed by the article "el", is formed "del"-
"Viste la foto del parque natural"? --- USED is a proper and "short" way


DIFFERENCE:
"de el" is not well said and written so it is ONLY used when "el" indicates a city or place that has "el" in its name.
EXAMPLE: "El Paso" is a place that has "El" in its name, so it can be written like this: Ella es originaria de El Paso, Texas.

It is important not to confuse "el" (the) with "él" (he)." If the pronoun is used, the contraction should not be carried out.
For instance:
"Ese perro es de él". RIGHT
"Ella dice que es de él. Sin embargo su actitud dice lo contrario". RIGHT

"Del" is used when "de" is followed by "El".
EXAMPLE: Vengo del centro de la ciudad. ("de is followed by "el" centro", it becomes "del")
