I'm currently watching the drama Jin) , which is set in the Edo period. There's an oiran named Nokaze from Yoshiwara who uses the suffix (I think it is a suffix) りんす (rinsu) quite often, such as in the phrase ありがとうござりんす (arigatō gosarinsu). I haven't heard any other characters use this suffix. Could anyone explain why? Is it a characteristic of oiran speech or perhaps a linguistic feature of the Edo period specific to a social group?
