Since words don't have a one-to-one mapping or anything--even in cases where the mapping of words themselves makes sense (and if often doesn't, as words in language say have different attachments for how to convey meaning)--this is still mostly a subjective translation problem; if you want to come close to this I recommend playing with apps like Pleco (for Chinese) that are designed to give you the source text in the original language and then let you click each word to get a dictionary definition (in your language) for each word (which of course isn't a single word and can't be, which is the problem with trying to get a "literal" translation). (I think Google Translate might have a mode like this?)
