I was browsing a famous social media website when I stumbled upon a post where someone was talking about how math teachers often speak and it mentioned some grammatical constructs which I often use in casual speech: "such that" and "thus".
English not being my native language (I'm French), I learned these from movies and online content mostly so I can't really tell if they are still "used" in day-to-day conversations.
I use "thus" a lot as a translation for "donc" to mean "implies", as in "The sky is blue, thus it is not red." I don't really know of any other word except for "so", but I often end up repeating it a lot so I replace it with "thus" sometimes.
"Such that" also seems familiar to me, its translation "tel que" being quite common in French.
