To which library does Lingq's add?

I’m doing Finnish lessons, but these texts also includes English words/translations. If I click on such word and mark it as Ling-word or known, to which library is the word added? The Finnish or the English (a language which I also study)?

@MarkSiip They will be added to your Finnish stats. However, in cases like that I suggest you simple ignore the words (trashcan button), and that will remove them from the stats.
