📝 Conjugation Notes
「再び (ふたたび)」 is an adverb and therefore does not conjugate.
🔊 Pronunciation Tips
The pronunciation is ふ・た・た・び (fu-ta-ta-bi). Ensure clear articulation of each mora. The pitch accent is generally flat or with a slight rise on the second “ta” depending on regional variations, but a flat pronunciation is generally safe and understood.
🧠 Memory Tips
Think of the kanji 再 (sai/futa) which means “re-” or “again.” Associate 「再び」 with formal “re-peat” or “re-turn” to distinguish it from more casual “again” words.
