step in

step in + to-infinitive

用法筆記

Intransitive — no direct object follows the phrasal verb. The reason for intervening is often added with a to-infinitive (e.g. stepped in to stop the fight).

常見錯誤

❌The manager stepped in the conflict.
✅The manager stepped in to resolve the conflict.
💡'step in' is intransitive; do not place a direct object or situation directly after 'in.' For the literal meaning of entering a space, use 'step into' instead.
