All words ending in “tion” or “ty” are both French and English. Apart from that, English gets many words from both Dutch and French that are similar. But there is no effort to exploit this because so many people are brainwashed to believe you should forget the existence of your 1st language when learning a new one.
I am firmly outside of that school of thought. When someone uttered the opening sentence of this post to me, I probably learnt ~6000+¹ words in French in 5 seconds. You cannot beat that. This would have taken years of playing charades using the popular immersion teaching style.
So the question is, are there any language learning tools whereby you specify two langauges and it produces a list or dictionary of true friends? The idea is that you can make a quick gain in vocabulary before progressing into unfamiliar/alienating words.
There are instances where I am writing a bilingual paper in English and French. The French column is a machine translation. Knowing some French (but not fluent), there are situations where the translation tool chooses a synonym for a true friend. If the machine had chosen a true friend, it would be easier for me to verify the quality of the translation and also easier for me to learn from. Considering my reader(s) are often native French and /possibly/ decent with English, there are also situations where I fail to choose an English word that would be easier for a francophone. So it would be useful as well if a translation tool would reverse the French back to English while trying to select true friends in English.
Furthermore, a reader of my French-English text may be a native Dutch speaker. So I would like an translation tool that adds some secondary gravity toward choosing English-Dutch friends when English-French falls short. Or another way to state this: I want a bilingual text that minimises the frequency of unique original words that are not borrowed by any of the relevant languages.
I realise gravitating toward true friends may cause a longer text in some cases, so I suppose I would also want to set a threshold of tolerance on additional words or syllables. In the end there would be some manual effort in the end anyway.

I think it must be quite complicated to implement. Torrents traditionally work on static data. An ISO image or mpeg4 doesn’t change, so the hash locks in the content and makes it possible to share pieces and assemble them with integrity checking. I have no idea how they are doing that with a webpage, which could potentially change every second. I don’t know if they have a way to add updates to a torrent of an existing page, or if they construct a new torrent on a snapshot basis.
