📝 Conjugation Notes
Verbs: Conjugate to the て-form. (e.g., 行く → 行っては, 食べる → 食べては) い-Adjectives: Replace い with くて. (e.g., 寒い → 寒くては, 忙しい → 忙しくては) な-Adjectives / Nouns: Attach では. (e.g., 静か → 静かでは, 学生 → 学生では) Note: For words ending in ん, では becomes んでは (e.g., 簡単 → 簡単では, but actually more common: 簡単では).
🔊 Pronunciation Tips
The は particle in 「〜ては / 〜では」 is pronounced as “wa,” not “ha,” as it functions as a topic/contrast marker here. Emphasize the negative nuance with a slightly falling intonation at the end of the first clause and a more definitive tone for the consequence.
🧠 Memory Tips
Think of 「ては」 as “leading TO a BAD outcome.” The “は” marks the problematic condition. For repetition, imagine “action -> consequence, action -> consequence” repeatedly. Visualize a negative domino effect.
