Proto-Altaic: *télki
Meaning: decking, duck-boards
Russian meaning: дощатый настил
Comments: Jpn. and Kor. may reflect a common derivative *télki-rV (although the source of -u- in the second syllable in Korean is not quite clear). Most languages point to the original meaning 'board covering', probably 'duck-boards in a boat or raft' (with a secondary development > 'plank covering in a sleigh' in Turkic.
