Use さえ in casual conversation.

Mistake 2: Mixing Formality Levels

Match formality throughout the sentence.

Mistake 3: Overusing in Modern Writing

❌ Every sentence: 今日すら...昨日すら...明日すら... ✓ Occasional use for emphasis

Even in formal writing, don't overuse.

Mistake 4: Wrong Context

❌ Comic book dialogue: やるぜ！これすら！ ✓ Comic book: やるぜ！これさえ！
