• In modern Japanese, Japonic なな (nana) is more common than Sinitic しち (shichi) (see Etymology 2) outside fixed compounds, which is similar to 四 (yo) but different from other numerals. The reason may be a superstitious connection to 死 (shi, “death”), or simply avoiding confusion with the similar sounding 一 (ichi) and 四 (shi).
