Spasell is a slang of Insubric language, spoken until the 19th century by inhabitants of Vallassina, when they used to go out from the valley for business and they didn't want to be understood by the people.
It is characterized by code-words conventionally defined basing on characteristics of the thing or on onomatopoeias; other words have an unknown origin.
It has been noted by Carlo Mazza, vicar of Asso, in his book Memorie storiche della Vallassina of 1796.
After a list of terms, the vicar proposes, as example, the translation of Pater Noster in this language, evidencing that it's totally incomprehensible also by the Insubric speakers.
Refilên el sbêg de stobold, e che no va stanzien nippa in del scimêe i nost lenarii, come anch'el nost'oden szabolda ai olter ghielma; Fêen taruscia la schigna che ne rusca el Naja de Tameu.
