Interesting expression in an anime that I can find only there and there is no information on the internet, that I can find, about its origin&history


In the Anime Honzuki no Gekokujo season 2, episode 4 from 19:56 onward the
main protagonist says "Arigatou Gozaimasu", to thank the high priest and is
immediately corrected by him with something that, at least I hear as -
"Arigatou Zongdzi-masu".

After extensive search on the internet and discussions with at least two
people that speak Japanese, at various levels, I found that there is no such
phrase in Japanese, yet I still hear it in a Japanese anime, voiced by
Japanese actors...

I found that Zongdzi is a rice dumpling, searched for all words and
expressions that can end on "masu"(and since this is a polite ending there are
a lot of them), checked in few online Japanese-English dictionaries but
couldn't find anything.

In the English subtitles version it was translated as "Please accept my
deepest gratitude" and was specified that this is a way for a noble women to
thank for something. I searched the web for a direct translation of the quoted
phrase in Japanese and found quite a few of those, but nothing that is even
remotely close to what I hear.

Please, if possible, can someone share what the phrase said in the anime
should look like, written in English, I am suspecting it is not Zongdzimasu,
and if it wont be a lot of additional work the phrase history and
applications.




The man in the video says ありがとう存じます, where
[存ずる【ぞんずる】](https://dictionary.goo.ne.jp/word/%E5%AD%98%E3%81%9A%E3%82%8B/) is
a humble verb for 考える. You may have heard (～と)存じ上げます, which is more common.

That said, ありがとう存じます is not something usually said by real modern Japanese
speakers (including "upper class" speakers). When something more stilted than
ありがとうございます is necessary, people usually say 感謝申し上げます, ありがたく存じます, etc. There is
usually nothing wrong with the girl saying ありがとうございます in this situation, so I
feel this scene is meant to emphasize the weirdness of 貴族言葉 in this world.

( **EDIT** : Looks like there are several native Japanese speakers who are
wondering if ありがとう存じます used in this anime is a real phrase. In my opinion, it
might have been a valid expression 150 years ago when
[ウ音便](https://japanese.stackexchange.com/q/24217/5010) as in 悲しゅうありません and
嬉しゅうて喜ばしゅうて was a norm among upper-class ladies, but it's unnatural at least
in today's standard Japanese.)

Japanese has no sound that is romanized as "dzi", so you can get almost
nothing related to Japanese by searching with this spelling. What you heard is
just one of the allophones of じ ("ji" in Hepburn romanization, "zi" in
kunrei). See: ["z" sound, which to
choose?](https://japanese.stackexchange.com/q/68584/5010)
