How to say "Eager" in Japanese

When translating "eager" into Japanese, you must choose carefully between 懸命な and 懸命. In Japanese, 懸命な (けんめいな (kenmeina)) is typically associated with "eager, earnest, desperate, with all one's might" (Syllabus Level: N2) and represents Describes making a strenuous effort or doing something with utmost diligence, often in a difficult situation. Usually used adverbially with 〜に. On the other hand, 懸命 (けんめい (kenmei)) maps to "eager, earnest, assiduous, desperate, working hard" (Syllabus Level: N2) and represents Refers to putting all one's effort into something, often in a difficult or critical situation. Can be used as 懸命に. A literal translation of "eager" can often sound unnatural to native Japanese speakers if mixed up!
