How to say "genuinely" in Japanese

• 素ですで
  adverbCovers 'genuinely' in the sense of a sincere, unfeigned reaction, as in genuinely meaning what one says. Colloquial and less common; it often suggests acting without putting on an act.
• 真にしんに
  adverbMatches 'genuinely' as 'truly' or 'indeed', used for something genuinely felt or truly the case, often in slightly formal or written contexts. A somewhat literary choice.
  これは真しんに最善さいぜんの方法ほうほうだ。↗

  This is the very best method.
• 普通にふつうに
  adverbIts glosses point to 'by normal standards' or 'sufficiently', so 'genuinely' here is marginal: it means something actually meets ordinary standards, as in genuinely good, rather than heartfelt sincerity.

Use 「素で」 for a plain, unadorned reaction, 「真に」 for sincere or heartfelt genuineness, and 「普通に」 when something is genuinely good 'by normal standards'.
