What Wiktionary says
Quoted line by line from Wiktionary's Etymology section for this reading, taken from one dated dump so it can't change underneath us. Nothing below is paraphrased.
- “As a surface analysis, this is a compound of 御 (o-, honorific prefix) + 母 (kā, “mother”) + さん (-san, honorific suffix).”
- “Historically, this represents a sound shift from older term o-kaka-sama, itself a compound of 御 (o-, honorific prefix) + 母 (kaka, “mother”) + 様 (-sama, honorific suffix).”
- “/okakasama/ → /okkasama/ → /okaːsama/”
- “/okakasama/ → /okkasama/ → /okaːsan/”
- “Attested in Osaka and Kyoto, with rare use in Edo (Tokyo), from the late Edo period, especially among upper-middle class households in Osaka.”
- “Usage became widespread in the 20th century after the Ministry of Education adopted お父(とう)さん (otōsan, “father”) and お母(かあ)さん for use in 尋常小学読本 (Jinjō shōgaku dokuhon “Standard elementary school reader”, 1903).”
