There is also a rarer prefix "mi-" (kun'yomi), which is mostly used in words related to gods and the emperor, such as "mi-koshi" (御輿, "portable shrine" in Shinto) and "mi-na" (御名, "the Holy Name" in Christianity). However, in this context it is often replaced by 神 ("god", also pronounced "mi-"), and then a further 御 (pronounced お-, "o-") may be added, as in 御神輿 ("o-mi-koshi"). Sometimes the reading is ambiguous—for example, 御霊屋 "mausoleum" may be pronounced either "mi-tama-ya" or "o-tama-ya". When pronounced as "mi-," the prefix is usually written in kanji (unlike "o-" and "go-", which are very frequently hiragana), but in some case it is written in hiragana, with a notable example being "mi-hotoke" (御仏, "Lord Buddha") often being written as み仏, partly to avoid confusion with the incorrect reading *"go-butsu".
