Explanation
Indicates that something is worthy or sufficient to be called/used as ~; 'worthy of', 'enough to ~'.
Formation
Noun/Verb-dictionary form + に足る + Noun
Detailed explanation
The classical pattern 'Noun + に足る + Noun' or 'Verb + に足る + Noun' means 'something is worthy of or sufficient for ~.' For instance, '信頼に足る人物' means 'a person worthy of trust.' It’s different from the everyday verb 足りる ('to be enough').
