Dictionaries and resources for translation of mathematical terminology Nowadays English seems to be the most frequently used language in mathematics. (Although plenty of papers and books are published in other languages, e.g., Russian, French, German and Chinese.) 
However, mathematics is taught many other languages and there are occasions when we need a translation of some technical term, which is well-known in English, to other language.

*Are there some dictionaries and other resources useful for translating from English to other languages?
  


There is somewhat similar question devoted specifically to Russian language: What resources are there for learning Russian math terminology?
One of the reasons I am asking this is this question which appeared recently at meta. In fact, the OP suggests in one part of this question creating some a kind of mathematical dictionary here at MSE.

For Russian-English dictionary, try Lohwater: Russian-English Dictionary of the Mathematical Sciences. 
Moreover, in some cases, checking interwiki links at Wikipedia can be also helpful.
