About んがため(に)

んがため is a grammar pattern used when indicating that something is being done 'for the purpose of (A)', or 'with (A) as the goal'. ん comes from an abbreviation of む, which is a classical auxiliary verb used to show intent or strong will in the same way as う and よう in modern Japanese. ん is then followed by が, and the noun ため 'sake', or 'purpose'.
ん connects to the indeterminate form of verbs (ない stem). Either の or に will usually come after んがため, depending on whether it is followed directly by a noun, or a statement linking to a verb.

  • ()(のこ)りの商品(しょうひん)()んがための作戦(さくせん)(かんが)えたが(なに)(おも)いつかなかった。
    I tried to come up with a strategy in order to sell the unsold goods, but came up with nothing.
The meaning of む is kept in ん, as this grammar structure will imply the speaker's will to achieve the goal of (A). As む expresses intent, the verb that ん is attached to must be something that can be controlled by the speaker.
Like most classical structures that interact with する, the more old-fashioned せ will be used as the base, rather than し.

    I am little confused about this sentence.
    I thought that the nai form of 為さる was 為さらない and hence it would be 為さらん. Is this a special case?

    ah of course, that makes a lot more sense. I was just blindly following the prompt word of 為さる, that was with the sentence. thanks Neko
