Something that always helped me was to look for similar words in my native language (or another language I know a little of) and make that the mental link rather than the one you typically see in translations. In German, window is "fenster" and in French it is "fenetre" (with some symbol over the second e indicating that there used to be an S before the T in old French). So that makes "fenetre" easier for me rather than remembering it directly as "window". In German, "flasche" is usually translated as "bottle". I remember it is "flask" first and foremost, which makes it easier for me.

I also transliterate rather than translate -- ie translate word for word instead of translating it actually into the grammar of my native language. When I took classical Greek, we had interlinear bibles that showed each word in English below the word in Greek. I had no trouble making sense of this, though it didn't make sense to other people. I was the only person in my Greek class who could read a passage in Greek and then tell you what it said in English. I was the most fluent person in that class. It also helps me familiarize myself with the grammatical differences between two languages.

Good luck with this.
