Tohu (1] Toht; 2] Tohk; 3] Tohu)
1] Birch bark; 2] Stern of small boat; and 3] Mist, haze. The earliest-known written document in Finno-Ugric – Tohtkiri (birch bark letter) No.292 – was carved on birch bark in the first half of the 13th C in a dialect of the Olonets Karelia region. Although its meaning is far from clear (jumolanuliinimiži | nulisě[x]anoliomobu | [xu]molasudьnipoxov[i], QED), it seems to involve God and arrows, and may well be an incantation or ‘thunder spell’; Tohtkiri No.403, incidentally, has been said to be a “Finnic-Slavic business travelers’ lexicon” although with only six words cheat-sheet may be a better description. Street forms a loop off Kase, so 1] is the most likely.
