📝 Conjugation Notes
Remember the negative stem is used (equivalent to the form before ない in the ない form). For Godan verbs, change the う-ending to the あ-line sound (行く→行か). For Ichidan verbs, remove る (食べる→食べ). Irregulars: する→せ, 来る→こ.
🔊 Pronunciation Tips
Pronounced “zaru o enai”. The を (wo) particle is pronounced like お (o).
🧠 Memory Tips
Think of “ざる” as an old-fashioned negative (“not doing”) and “を得ない” as “cannot obtain [that state of not doing]”. So, “cannot obtain the state of not doing it” means “have to do it”. Connect “ざる” to the older negative forms like べからず (bekarazu) or the negative in classical texts.
