In the sentence ‘I don’t ask for other actions except for greeting toward an acquaintance,’ the use of ‘for’ instead of ‘a’ has been pointed out as an error. But why is ‘a’ the correct choice here? Let’s break it down:
1. Understanding the Sentence Structure
The phrase ‘ask for’ is commonly followed by a noun or noun phrase that represents the thing being asked for, such as ‘I don’t ask for help’ or ‘I don’t ask for directions.’ In your original sentence, ‘other actions’ is what is being asked for, and the preposition ‘for’ is correctly used with ‘ask’ to indicate the object being requested.
2. Why ‘for’ is Incorrect in the Context of ‘greeting’
However, when you say ‘except for greeting,’ the structure changes. ‘Greeting’ here refers to the action itself, not an object. The preposition ‘for’ is not needed before actions like ‘greeting’ because it doesn’t function in the same way as asking for an object. Instead, ‘greeting’ is used as a gerund (a verb acting as a noun), and it does not require the preposition ‘for’.
3. The Correct Use of ‘a’ in the Sentence
By removing ‘for’ and using ‘a’ before ‘greeting,’ you correct the sentence structure: ‘I don’t ask a greeting toward an acquaintance.’ This implies you don’t specifically request a greeting, but you expect the greeting as part of the general actions when meeting an acquaintance.
4. Key Points About Prepositions and Gerunds
In English, certain verbs and phrases require specific prepositions or omit them altogether when followed by gerunds. For example, ‘ask for’ is used when requesting an object or a specific thing, while ‘ask a question’ or ‘ask an acquaintance’ does not require a preposition because they are actions that are not requesting a specific object.
5. Conclusion: The Importance of Correct Preposition Usage
Understanding when to use prepositions and when not to is crucial in English. In your sentence, ‘greeting’ does not need the preposition ‘for,’ and thus ‘a’ is used to make the sentence grammatically correct. This helps clarify the meaning and structure of the sentence, making it more precise and understandable.
