“naisho” vs. “himitsu”：Did You Notice How to Use These?
What is the difference between “内緒(naisho) and 秘密(himitsu)”? Which is a much stronger meaning? After reading this, you would be answering this question. Let me introduce what their subtle differences are and how you correctly use them such as native speakers today!
内緒 (naisho) and 秘密 (himitsu)
Secret / 保密, 秘密 / 비밀 / Bí mật, Bí mật
“内緒(naisho) and 秘密(himitsu)” mean “Secret” and which has been used as the meaning of “a piece of information that is only known by one person or a few people and should not be told to others”. The basic way to use it is “___は内緒/秘密です。(___ is a secret.)”, etc. For instance, “これは内緒/秘密です。(This is a secret.)”, etc. The tips for using them are that although “内緒” and “秘密” are the same meaning, “秘密” is a stronger meaning than “内緒“. For instance, a girl/woman says that “彼氏に内緒でランチに行った。(I went eat lunch secretly from my boyfriend.)” which I think “she wanted to go eat expensive lunch or something?”, whereas “彼氏に秘密でランチに行った。(I went eat lunch secretly from my boyfriend.)” which I think she probably cheats on him. Both of them mean she has a secret, however, basically “秘密” has a stronger meaning than “内緒“. Furthermore, “内緒” tends to be used in daily conversations as casual and “秘密” tends to be used as formal. Everyone could use “内緒 and 秘密” as casual, polite and formal such as “内緒/秘密にしておくね/よ。(Just between us.)” as casual and “内緒/秘密にしておいてください。(Just between us.)” as polite and formal.
“どれがいい？(Which do you prefer?)”/”どっちがいい？(Which do you prefer?)” as casual and “どれがいいですか？(Which do you prefer?)”/”どっちがいいですか？(Which do you prefer?)” as polite and formal. Lastly, “どっち” is used as casual and polite and “どちら” is used formal which are the same meaning.
