In English grammar, choosing between verb forms can sometimes be confusing. A common question arises from sentences like: ‘With so many people registered for his seminar, Mr. Kato decided to have his handouts printed by a printing company.’ Why is ‘registered’ used here instead of ‘registering’? Let’s break it down!
Understanding the Structure of the Sentence
The sentence is structured as follows: ‘With so many people registered for his seminar.’ This part acts as an introductory clause providing additional information about the people involved in the seminar. The main verb of the sentence is ‘decided,’ which is the action Mr. Kato took. Now, let’s focus on the phrase ‘so many people registered for his seminar.’
The Role of ‘Registered’
In this context, ‘registered’ is a past participle used as an adjective. It describes the people who are already signed up for the seminar. The use of the past participle ‘registered’ emphasizes that the registration happened before the moment in question—before Mr. Kato made his decision to print the handouts. It indicates a completed action or state of being at the time of the decision.
Why Not ‘Registering’?
‘Registering’ is the present participle form of the verb ‘to register.’ Using ‘registering’ would suggest an ongoing or continuous action, which doesn’t fit the context of the sentence. The idea is not that people are still in the process of registering when Mr. Kato makes his decision, but rather that they have already completed their registration. Therefore, ‘registered’ is the correct form because it reflects a completed action.
Other Examples of Past Participles Used as Adjectives
We often use past participles in a similar way to describe completed actions or states. For example:
1. ‘The broken window was repaired quickly.’ (The window is broken, the action of breaking is completed.)
2. ‘The written report was submitted.’ (The report is written, and the action is finished.) These examples show how past participles provide essential context about actions or states that have already happened, just like ‘registered’ in the original sentence.
Conclusion
In the sentence ‘With so many people registered for his seminar,’ the use of ‘registered’ is grammatically correct because it describes a completed action that took place before Mr. Kato made his decision. ‘Registering,’ on the other hand, would imply that the action is still ongoing, which doesn’t fit the intended meaning. Understanding how and when to use past participles like ‘registered’ helps clarify the timeline of actions and events in English grammar.
