FOR and its use

Use ‘for’ properly.  Eso !!! : properly= adecuadamente, como es debido, con propiedad,  como Dios manda.

For is not used  to express the aim (objetivo, finalidad) except if you use it before a noun.

We went to the restaurant for a delicious meal.

In other cases, with a verb, you’ll use the infinitive:

We went to the restaurant to have a delicious meal.

OJO !!!

for+to…. NUNCA.
