This is not the question you think it is.
This trait does not give you access to racial traits of other races but to Traits that are in the Race category within Traits. The same place that you got the trait Adopted from, just not a Social Trait but a Race Trait. Now, with that out of the way.
Adopted has the following text:
You were adopted and raised by someone not of your actual race, and raised in a society not your own. As a result, you picked up a race trait from your adoptive parents and society, and may immediately select a race trait from your adoptive parents' race.
So you are not of this race, but you were raised within it. It doesn't suggest how long, but if it's long enough to have some societal trait as part of your character why is there also not an option for the specific language of that race/ethnicity and only that language?
So if your adopted parents were Elves you get access to elvish, this is not to say you have it automatically, but that you could take it. You should even have the option to loose your own racial language and use that the gain the adopted racial language.
If this actually exists could someone please point me towards this.
