N1 Purpose and Means
~んがために: meaning, usage and examples
~んがために means: in order to... (strong, often extreme, purpose).
How to form it
<Verb ない-form without ない> + んがために / んがための + <Noun> (する → せんがために)
Examples
夢を実現せんがために、彼は故郷を離れた。
In order to make his dream a reality, he left his hometown.
金メダルを取らんがために、血のにじむような努力をした。
He made a painstaking effort in order to win the gold medal.
自らの責任を逃れんがために、彼は平然と嘘をついた。
To escape his own responsibility, he lied without batting an eye.
視聴率を上げんがために、番組は過激な演出を繰り返した。
To boost its ratings, the show kept resorting to extreme stunts.
When to use it
Expresses a very strong, single-minded purpose: in order to achieve X, at any cost. Example: 勝たんがために、ルールを破った (he broke the rules just to win). It often appears when the writer views the means as excessive or the motive as self-serving, but it can also describe great effort toward a dream.
Nuance
Literary and stiff; used in written commentary, novels and formal speeches, not in conversation. It frequently carries criticism of the means. Like べく, the main clause is an intentional action, never a request. The forms 言わんばかり and んがため share the classical ん (= う, will).
Compare
んがために is the strongest purpose form: 売らんがための広告 (an ad made only to sell). べく is formal but neutral: 売上を伸ばすべく努力する. ために is the everyday version. Use んがために when the purpose seems to justify extreme means.
Tip: Build it from the ない-stem: 取る → 取らんがために, 行く → 行かんがために. The one exception is する → せんがために.
