‘and’ and ‘but’
- ‘and’ and ‘but’ join clauses into a sentence.
- Do not start a new sentence with ‘and’ or ‘but’.
- Do not put a comma or a full stop before ‘and’, ‘but’ or ‘or’.
- Do not put a comma after conjunction introducing a clause, e.g. He told me that he was too tired to watch the movie.
Traditionally, ‘however’ was regarded as a conjunctive adverb or a discourse marker, not a conjunction. In other words, ‘however’ marks a relationship between sentences or ideas and does not join clauses into a sentence, i.e. it is not conjunction.
However, the Macquarie Dictionary notes that there is a modern trend to use it as conjunction and gives the example: I thought he was coming, however, he failed to arrive.
