Grammar Rule: Prohibited From + Gerund
The verb 'prohibit' is typically followed by the preposition 'from' and a gerund (the '-ing' form of a verb). This structure indicates that an action is forbidden.
Analyzing the Sentence Structure
The sentence requires a phrase to explain what people were forbidden to do with their vehicles near the entrance.
- Prohibited to park: Incorrect. This structure is not standard English usage for prohibition.
- Prohibited from parking: Correct. This follows the standard structure: Prohibit + Object + From + Gerund. It means people were not allowed to park.
- Prohibited parking: Incorrect in this specific sentence structure. While "Parking Prohibited" is a valid sign, the sentence requires a verb phrase after "prohibited".
- Prohibited to have parked: Incorrect. This structure is grammatically flawed for this context.
Completing the Sentence
Applying the rule, the correct phrase is 'from parking'. The completed sentence reads:
People were prohibited from parking their vehicles near the entrance of the main administrative building.
