Here's how:
* It connects two parts of a sentence, showing a difference or exception.
* It often introduces a contrasting idea or situation.
Example:
* "All the students passed the exam, except for John."
In this sentence, "except for" connects the two parts:
* All students passed the exam.
* John did not pass the exam.
Other ways "except" can function:
* Preposition: "Everyone was invited to the party except John."
* Adverb: "I like all fruits, except bananas."
While "except" can function in different ways, it is often used as a conjunction to show contrast.
