In English, the sentence ‘I don’t know where to start with that’ is a common structure that uses an infinitive after ‘where’. This sentence may raise a question about why the infinitive form ‘to start’ is used instead of the gerund ‘starting’. In this article, we’ll explain why the infinitive is necessary in this case and why the sentence cannot use ‘starting’.
1. The Role of the Infinitive after ‘Where’
The use of the infinitive ‘to start’ after ‘where’ is a standard grammatical structure in English. When the question word ‘where’ is used in combination with a verb like ‘know,’ the infinitive is often used to express the action that someone doesn’t know how to perform. The construction typically expresses a sense of purpose or intention.
2. Why ‘Starting’ Isn’t Correct in This Context
Using the gerund ‘starting’ in this case would be grammatically incorrect. The gerund is typically used when the action is being discussed as a general concept or a continuous process, but in this case, the sentence is about a specific action that needs to be performed, not a general or ongoing activity. Therefore, ‘to start’ is the correct choice to indicate the specific action the speaker is unsure about.
3. Infinitive vs. Gerund: When to Use Each
In English, the choice between an infinitive and a gerund depends on the verb and the context. For verbs like ‘know,’ ‘want,’ or ‘need,’ the infinitive is often used to express intention or a specific action that follows. The gerund, on the other hand, is used with verbs like ‘enjoy,’ ‘recommend,’ or ‘consider,’ where the focus is on the action itself rather than its purpose or intention.
4. Practical Examples and Further Clarifications
Here are some additional examples to clarify the difference:
- ‘I don’t know where to go next.’ (Correct usage of the infinitive)
- ‘I enjoy going to the park.’ (Correct usage of the gerund)
- ‘She doesn’t know where to start her project.’ (Infinitive used to express a specific action)
Summary
The reason ‘I don’t know where to start with that’ uses the infinitive ‘to start’ is that this structure expresses a specific action or intention, which is typical when using verbs like ‘know’. The gerund ‘starting’ would be incorrect because it suggests an ongoing action, which isn’t the intended meaning here. Understanding when to use the infinitive versus the gerund helps improve clarity and correctness in English grammar.
