Tetraphobia, the Shee and me
Tetraphobia (from Ancient Greek (tetrás) 'four', and Ancient Greek (phóbos) 'fear') is the practice of avoiding instances of the digit 4. It is a superstition most common in East Asian nations. Many buildings in Asian countries don't have a fourth floor. If hospitals do, then they never keep patients on the fourth floor. The 4th floor is missing because there is a very similar pronunciation of "four" and "death" in many languages that sounds like "shee." The words "four" and "death" are pronounced the same in the following languages: Proto-Sino-Tibetan *b-ləj *səj Old Chinese /*s.lij-s/ /*sijʔ/ Middle Chinese /siɪ H / /sˠiɪ X / Mandarin Chinese sì sǐ Wu Chinese ( Shanghainese ) sy² sy², shi² Cantonese sei³ sei² Hakka si³ si⁴ Min Nan ( Hokkien ), Taiwanese sì, sù sí, sú Vietnamese tư, tứ tử Korean sa sa Japanese shi shi The pagan Irish worshipped the Side (also pronounced "shee,") i.e. the earth-god
