Translation guide
In Japanese, expressing 'new discovery' depends on context. For scientific or factual discoveries, use 発見 (hakken). For personal realizations or emotional discoveries, use 気づき (kizuki) or the verb 気づく (kizuku). In casual speech, わかった (wakatta) or 知らなかった (shiranakatta) often convey the sense of a new realization.

The phrase '新しい発見' (atarashii hakken) is grammatically correct but often redundant because 発見 already implies newness. Use 新発見 for emphasis in formal writing, or simply 発見.
