what should go between

yo encuentro ____ la amabilidad?
yo busco ____ amigo que son amable

would it be por or para?

The way these 2 sentences are set up, it seems awkward to put either in that blank. Let me see the directions given for this exercise and any modelo/example you might have. Otherwise:

Yo encuentro la amabilidad = I find friendliness.

Yo busco a un amigo que es amable. You could use "personal a" here but the sentence is incorrect as you have it. "amigo" is singular and the verb is plural "son" with a singular adjective.

Sra

P.S. Here are some things I tell my students and most of it is very close to what Kade told you.

THE USES OF POR AND PARA:

PARA means: for, in the sense of purpose, use, destination, for (by) a time in the future, considering that (in spite of the fact that). It is also translated: in order to, to, by. Many times you an substitute the word "a" (to, toward, and not the Personal "a") imstead of "para."

Para also means "Para ser"

POR means: for, in the sense of in exchange for, period or extent of time, for the sake of.

Por also means: for, after the verbs: ir, enviar, luchar, llamar, preguntar

Plr also means: during and is often translated by in.

Por expresses the idea of rate and is equivalent to "per."

Por also means by, through, along

Usually you can substitute "porque" for "por"

If you would like lots of exercises where you must choose POR or PARA, let me know and I'll be happy to type them out for you. That is actually the BEST way to be sure you DO understand the differences between the 2 words.

***The following verbs are not followed by "por" or "para" because the word "for" is part of the meaning of the verb. They are:
buscar = to look FOR, to seek
esperar = to wait F

buscar, to await
pedir = to ask FOR, to request

In the sentence "Yo encuentro ____ la amabilidad?" you should use the preposition "en". The correct phrase would be "Yo encuentro en la amabilidad" which translates to "I find kindness in."

In the second sentence "Yo busco ____ amigo que son amables" you should use the word "un". The correct phrase would be "Yo busco un amigo que son amables" which translates to "I am looking for a friend who is kind." In this case, "un" is the indefinite article used before a masculine singular noun.
