Key Differences

"After" is a versatile preposition or conjunction used to describe something occurring subsequent to a specific time or event. On the other hand, "thereafter" is an adverb focusing more precisely on following up an event in a chronological sequence, often used in more formal or legal contexts.
In usage, "after" can initiate a phrase or clause, linking actions or times with flexibility. Whereas "thereafter" typically appears in more structured narratives or written documents to denote a strict sequence following an initial event.
For daily conversation, "after" is much more commonly employed due to its general nature and easier syntax. Meanwhile, "thereafter" might be reserved for written reports, legal documents, or formal speeches, highlighting its formal tone.
In terms of placement within a sentence, "after" can be more flexible, appearing at the beginning or in the middle of sentences. In contrast, "thereafter" usually follows the main clause or is used at the start of a new sentence to continue a previously established timeline.
The implications of "after" can be immediate or long-term without specific constraints, reflecting its broad application. Conversely, "thereafter" implies a direct continuation and often a close temporal relationship to the preceding events.
