Here's how:
* As a conjunctive adverb: When "but" connects two clauses, it can be considered an adverb. It typically expresses contrast or opposition.
* Example: "I wanted to go to the party, but I was too tired." (Here, "but" connects the clause "I wanted to go to the party" with the clause "I was too tired," and it shows a contrast.)
* As a coordinating conjunction: While "but" is primarily a coordinating conjunction, it shares some features with conjunctive adverbs, especially in conveying contrast.
* Example: "It was a difficult journey, but we made it." (This example is similar to the previous one, showing the contrasting nature of "but.")
However, "but" doesn't always act as an adverb. It often functions as a coordinating conjunction, connecting words, phrases, or clauses.
Key takeaway:
Although "but" is primarily a conjunction, it can also function as an adverb when it connects clauses and expresses contrast or opposition.
