〜べからず/〜べからざる : 〜してはいけない・禁止


By the way この上に書いてある誠さんのノートに間違ってることに気づきました。名詞の前につくというのじゃなくて、動詞の前につく形のほうが正しいとおもいます。
Etymologically, this is adjective 可(べ)し in 連用形 beku, to which 在(あ)り is appended, forming bekuari > bekari. Then, to its 未然形 bekara, the classical verb of negation ず is added, forming bekarazu. Further, 在り can be added again, resulting in bekarazari, whose 連体形 is bekarazaru. Also recall that 連体形 is used for verbs before nouns (attributive usage) and 終止形 for ending sentences.

    dcis this extremely formal? it sounds like it... 
    bamboo4It is not only formal but it is somewhat archaic. 
    blabbyI've been studying Japanese for almost 3 years and I've never come across this grammar except in text books...I asked my (young) Japanese friends and they have no idea. But if you do a Google search, there are lots of examples.

    It is always followed by a noun. もの, こと, 行為, etc.
    bamboo4You can also construct a phrase combining it with various suffixes. べからざるや、べからざるか、べからずとする、etc.
    This must be worth remembering, but few Japanese use it in everyday speech.
    I think that most Japanese usually say:




    jimmysealActually, the 終止形 form is べし, and it conjugates like an adjective, meaning the 未然形 is べから.

    As blabby hinted, use べからざる before nouns, and べからず at the end of sentences.
