Why telonio

A telonium was a customs house — the booth on the road or in the harbour where duty was assessed. The word is Latin, borrowed from the Greek τελώνιον; in the Vulgate, Matthew sits „in telonio“.

What grew out of it matters more. Czech clo, German Zoll, English toll and Dutch tol all descend from that same root, Czech by way of Old High German zol. One word, from which each country made its own.

That is what this tool does: it looks for the common ground beneath 27 national layers. Telonio is the place; the declarant is the person who files there.
