6. Common Mistakes and Tips
Common Mistakes
- Confusing with 足る (taru):
- Some learners might confuse 足りる (tariru) with 足る (taru), which also means "to be sufficient" but is less commonly used in modern Japanese.
- Incorrect Particle Usage:
- Using を (wo) instead of が (ga).
- Incorrect: お金を足りない。
- Correct: お金が足りない。
Tips for Remembering
- Mnemonic Device: Think of 足 (ashi) meaning "foot," and imagine you need to "step up" to meet the required amount—if you can't, it's 足りない (not enough steps).
- Remember that 足りない always involves the particle が (ga) to mark the subject that is insufficient.
