よくある間違い：
Learners often say *"I am unsure to go"* instead of *"I am unsure whether to go"* or *"I am unsure about going"*. Another common issue is overusing "unsure" where native speakers more often say "not sure" in casual speech (e.g. *"I'm not sure"* is more natural than *"I'm unsure"* in many everyday contexts).
