Where this word comes from
Likely a borrowing from Estonian siil, from Proto-Finnic *siili, from Proto-Finno-Ugric *śijele. The hedgehog is a recent introduction to most of Finland: the first reported sightings of hedgehogs outside of the southern coast date to the second half of the 19th century. Its traditional distribution in Finnish is restricted to dialects alongside the southern coast, which hints at an Estonian borrowing. The word is first attested in 1835 in the Kalevala. Compare Erzya сеель (sejeľ).
