に足る

に足る is a formal, evaluative expression meaning that something has enough merit, value, or sufficiency to justify or warrant a certain action or conclusion. It is often used in written or formal contexts to judge whether a thing (usually a noun) is worth doing, relying on, or deserving of something. It emphasizes adequacy and merit rather than just basic existence. It tends to sound more literary or official than everyday speech, and is commonly used with nouns describing content, credentials, or evidence. Example usages: - この資料は研究を進めるに足る内容だ。 This material is sufficient to advance the research. - 彼の実績は社長に就任するに足る人物だ。 His track record is worthy of being appointed as president.
