What Does “After Which” Mean?

At its core, “after which” acts like a bridge between two related events or actions, telling us that one thing happens, and then another follows. It’s a phrase made of a preposition (after) plus a relative pronoun (which), combining to create a smooth connection.

• It usually refers to time or sequence, answering “what happened next?”
  
• It often introduces the second action or event following the first.

Real-life examples

• She finished the report, after which she submitted it to the manager.
  
• We visited the museum, after which we went out for dinner.

In American English, people use “after which” mostly in written or formal speech, but knowing it helps you understand and craft complex sentences effectively.

Grammar Rules for Using “After Which”

Getting the grammar right with “after which” is straightforward but important for clarity and flow.

Sentence structure

The phrase links two parts of a sentence:

[First event/action], after which [second event/action].

Usually, you place a comma before “after which” to separate the two clauses.

Example:

• The meeting ended early, after which everyone left the office.

Comma use

Place a comma right before “after which” unless the sentence is short and simple.

Formal vs casual

• In formal writing (academic papers, official emails), “after which” fits perfectly.
• In casual conversation, people often use “then” or “after that” instead.

Common mistakes Americans make

• Forgetting the comma before “after which”
• Trying to start sentences with “after which” without a preceding clause
• Mixing “after which” with unrelated connectors like “because”
