Another prefix, pronounced "o-" （お〜） and potentially confused with 御〜 when written in hiragana, is 阿〜 "o-", which also has affectionate connotations, but is a separate term and not productive. It was previously used for endearment for women's names, and today is most notable in 阿多福／阿亀 ("o-ta-fuku," "o-kame", "moon-faced woman, homely woman"), which are frequently written as お多福／お亀, which may be mistaken (partially) for hiragana forms of ×御多福／×御亀. The character 阿 is more frequently pronounced "a," and used especially in words and names from Sanskrit, such as the "a" in the syllable "aum", hence unfamiliar in this use, creating the potential for confusion.
