loss cannot be avoided with certainty even in the case of conversations within one natural language. Imagine I read a paragraph to someone and ask them to rewrite it. Assuming the "someone" was not an expert in memory techniques so that they could not, as it were, "inscribe" the paragraph on their brain, the way they would remember the paragraph would be via its meaning. When they rewrote it, they would almost certainly use at least some different words and this would likely result in a small change of meaning.
