How to say "Very" in Japanese

When translating "very" into Japanese, you must choose carefully between 一生懸命 and いとも. In Japanese, 一生懸命 (いっしょうけんめい (isshoukenmei)) is typically associated with "very hard, with all one's might, diligently" (Syllabus Level: N4) and represents An adverb used to express putting maximum effort into something. Often used with verbs like 勉強する. On the other hand, いとも (いとも (itomo)) maps to "very, extremely (archaic/literary, often used with adjectives like 簡単, 容易, たやすい)" (Syllabus Level: N2) and represents An old-fashioned or literary adverb emphasizing 'very' or 'exceedingly.' It often adds a sense of ease or simplicity and usually precedes an adjective.. A literal translation of "very" can often sound unnatural to native Japanese speakers if mixed up!
