Abstract:
A method of using a created international language as an intermediate pathway
in translation between two national languages, wherein the first language is
translated into the created international language, the latter serving as a
bridge, which is then translated into the second language. In the present
method there are interpretive steps rather than a strict word for word
translation, without interpretation, which has proven falacious in the past.
I think this means that it does exist!
