Grammar Error Identification: Understanding "Ordered To" Usage

The question asks us to identify the grammatically incorrect part in the sentence: "The professor (I) ordered to (II) the students to go (III) out of the class. (IV)" We need to analyze each part to find the error.

Analyzing the Sentence Parts

Let's break down the sentence and examine each numbered part:

• Part (I): The professor
  This part introduces the subject of the sentence, "The professor." This is grammatically correct as it sets up who is performing the action.
• Part (II): ordered to
  This part contains the verb "ordered" followed by the preposition "to." The verb "order" is typically a transitive verb when it means to give a command to someone. A transitive verb takes a direct object without needing a preposition. In this context, "the students" are the direct object of the verb "ordered."
• Part (III): the students to go
  This part includes the direct object "the students" and the infinitive phrase "to go," which describes the action they are ordered to perform. This structure is generally correct for the verb "order" when followed by an object and an infinitive.
• Part (IV): out of the class.
  This is a prepositional phrase indicating the direction or place. This part is grammatically correct and completes the meaning of the sentence.

Correcting the Grammatical Error

The error lies in Part (II) "ordered to". The verb "order" in the sense of giving a command to a person or group does not require the preposition "to" before its direct object. Instead, the direct object should immediately follow the verb.

For example:

• Incorrect: The teacher ordered to the students.
• Correct: The teacher ordered the students.

Similarly, when "order" is followed by an infinitive (like "to go"), the structure should be: subject + ordered + direct object + infinitive.

Therefore, the correct sentence structure should be: "The professor ordered the students to go out of the class."

The preposition "to" is unnecessary and makes the phrase "ordered to the students" grammatically incorrect. Removing "to" makes the sentence grammatically sound.

Summary of Grammatical Rule

The verb "order" when used to mean 'to give a command to someone' is a transitive verb. It directly takes the person or group as its object. It follows the pattern: Order + somebody/something + to do something. Using a preposition like "to" before the direct object in this context is redundant and incorrect.

Based on this analysis, Part (II) is the grammatically incorrect section of the sentence.
