In English grammar, the word ‘after’ can serve as both a preposition and a conjunction depending on the context. If you encounter a sentence like ‘We will depart immediately after arriving at Nagoya,’ you might wonder whether ‘after’ is functioning as a preposition or a conjunction. This article will break down the different uses of ‘after’ and explain which one applies in this case.
Understanding the Function of ‘After’
The word ‘after’ is versatile in English and can be used in different ways. When used as a preposition, it typically connects a noun or pronoun to another part of the sentence, indicating time or sequence. As a conjunction, ‘after’ connects clauses and is often followed by a subject and a verb.
‘After’ as a Preposition
In the sentence ‘We will depart immediately after arriving at Nagoya,’ ‘after’ is functioning as a preposition. It introduces the phrase ‘arriving at Nagoya,’ which acts as a noun phrase. Here, ‘after’ shows the time relationship between the two actions—arriving and departing—indicating that the departure will happen following the arrival.
Prepositions like ‘after’ help establish temporal relationships between actions, events, or states, often providing more detail about when something happens.
‘After’ as a Conjunction
When ‘after’ is used as a conjunction, it connects two clauses. For example, in the sentence ‘After we arrived at Nagoya, we will depart immediately,’ ‘after’ connects two independent clauses. The conjunction ‘after’ is used to show that one event (departure) will follow another event (arrival) in time.
The key difference between a preposition and a conjunction is that a preposition typically requires a noun or noun phrase, while a conjunction connects full clauses.
How to Identify Whether ‘After’ is a Preposition or Conjunction
To determine whether ‘after’ is functioning as a preposition or a conjunction, you can look at what follows it. If ‘after’ is followed by a noun or noun phrase (like ‘arriving at Nagoya’), it is likely being used as a preposition. If it is followed by a subject and verb (like ‘we arrived at Nagoya’), then ‘after’ is a conjunction.
In the sentence ‘We will depart immediately after arriving at Nagoya,’ since ‘after’ is followed by the noun phrase ‘arriving at Nagoya,’ it is functioning as a preposition.
Conclusion
The word ‘after’ can serve both as a preposition and a conjunction, depending on the structure of the sentence. In the example ‘We will depart immediately after arriving at Nagoya,’ ‘after’ is used as a preposition to link the noun phrase ‘arriving at Nagoya’ with the main action, which is departing. Understanding how ‘after’ is used can help clarify the meaning of a sentence and the relationship between actions or events.
