So I just learned the kanji 皆. I knew the word beforehand (generally as みんな), but I want to know about proper usage/spelling as far as kanji/kana goes.
jisho.org says the following.
- 皆 is usually spelled みんな with an alternate spelling of みな. It is usually written in kana alone.
- 皆さん is only spelled as みなさん and makes no mention of being written in kana alone.
- 皆様 is only spelled as みなさま (with alternate kanji/kana combinations) and makes no mention of being written in kana alone.
Now, all of this sounds fine to me out loud. For example, I do think みなさん flows better than みんなさん would. But I want to know from people with more experience speaking/listening which versions they have heard more often.
