Use に足る for a formal assessment that something deserves an action or meets a sufficient standard.
The idea
Attach に足る to a verbal noun such as 信頼 or to a dictionary-form verb such as 検討する. Before a noun use に足る; as a predicate use に足ります, or に足りません for a negative judgment.
| Pattern | Example |
|---|---|
| 名詞+に足る | 信頼に足る |
| 動詞の辞書形+に足る | 検討するに足る |
| 否定 | 信頼に足りない |
Examples
- この資料は検討に足ります。This material is worthy of consideration.
- その報告は信頼に足りません。That report is not worthy of trust.
- 彼は尊敬に足る人物です。He is a person worthy of respect.
- この本は一読するに足る内容です。This book has content worth reading.
- その発見は注目に足ります。That discovery deserves attention.
- 噂だけでは判断するに足りません。Rumors alone are not enough to make a judgment.

Watch out
This is a judgment of worth or sufficiency, not simply ability. 信頼に足りない means unworthy of trust; it does not mean someone cannot trust.
