‘However’ as an adverb is a transition word. This means that it is used to connect to independent clauses. When used, it must be separated from the rest of the sentence with a comma. This can occur is a few ways:
Example:
I love to travel. However, it requires time and money. (Two sentences. ‘However’ introduces the second sentence. Must use a comma after use).
I love to travel; however, it requires time and money. (Two independent ideas separated by a semi-colon. Must use a comma after use).
I love to travel. It requires time and money, however. (Two sentences. Must use a comma before use).
‘But’ is a coordinating conjunction - a structure often used to connect ideas that contrast each other. Other examples of coordinating conjunctions are ‘Or’ and ‘And’. Commas are often used to separate longer or more complicated clauses. Shorter pairs of clauses are often connected without commas.
Example:
I love to travel but it requires time and money.
Some more examples of when these words can be used interchangeably because of their purpose - to indicated contrast:
- That’s a valid point, but I think we should go together.
- That’s a valid point; however, I think we should go together.
- That’s a valid point. However, I think we should go together.
