can do; worthy; worth doing
Expresses that something or someone is worthy of or enough to be considered in a certain way, or that an action is worth doing.
This pattern conveys that something meets the standard for being judged, trusted, or respected. It has a formal, written tone and is common in news, essays, and speeches. The verb form 足る is more literary, while 足りる is slightly more common in modern usage, but both are used in formal contexts. When attached to a verb, it often appears in phrases like 信頼するに足る (worthy of trust) or 読むに足る (worth reading). Note that the verb is always in its plain dictionary form, regardless of the subject or tense—the pattern itself carries the judgment.
