- From: This is a highly frequent grammatical error. While speakers of other languages often translate ‘from’ literally to mean protection away from a source, in English ‘from’ indicates physical origins, starting points, or separation (e.g., ‘escaped from the zoo’). It cannot be paired with ‘afraid’ to map an active phobia.
- In: This is incorrect. The preposition ‘in’ implies physical containment, inside boundaries, or deep involvement within an enclosed environment (e.g., ‘trapped in a room’). It breaks structural idioms when placed directly after ‘afraid’.
