If you spend some time working on Voynich yourself you'll find that it's actually fairly doable to come up with some translation where you can find a few words that seem to agree with each other. And when you allow yourself some permissions like unorthodox spellings or characters that can mean different things in different places, then it's not so hard to even be able to 'translate' a few seemingly reasonable sentences. This gives a lot of hope to the translator and any who follow them

So far none of these ideas have been shown to be applicable to the full text though. What you would expect with a real translation is that the further you get with your translation, the easier it becomes to translate more. But with the attempts so far is that we keep seeing that it becomes more and more difficult to pretend that other pages are just as translatable using the same scheme you came up initially. It eventually just dies a quiet death
