CJK Character 祕

It means secret, hidden, or mysterious. 祕 meaning in Chinese depends on the word around it: something withheld, hard to know, or kept as a guarded method.

The Shuowen Jiezi, an early Chinese dictionary of character forms, defines 祕 as divine or god-related. That is why does 祕 have 示 on its left: that part points to ritual and the divine, while 必 on the right gives the sound.

Why does 祕 sometimes become 秘?

They are variant spellings of one word. 祕 keeps the 示 side; 秘 uses 禾 instead. Taiwan’s education dictionary treats 祕 as the standard entry, while the 祕 Japanese old form is kept for older spellings and 秘 is expected in ordinary Japanese.

So the choice tells you about the source, not a new meaning. Keep 祕 when copying a Traditional Chinese text or an older Japanese spelling; type 秘 for normal modern Japanese.

What should I read when someone sends 祕?

Read “secret” first, then check the word around it. Someone sent me 祕 alone is usually a fragment, label, or typo for part of a longer word. A bare 祕 is a typed character, not a reaction, so ask for the sentence if there is no context.
