  • Usage notes

    * Beginning a sentence with a coordinating conjunction such as but' is considered incorrect by classical grammarians arguing that a coordinating conjunction at the start of a sentence has nothing to connect, but use of the word in this way is very common. It is, however, best to avoid beginning a sentence with '''but''' in formal writing. Combining sentences or using '''however''', '''nevertheless''', '''still''', or ' though is appropriate for the formal style. ** But this tool has its uses. ** This tool has its uses, however. ** Nevertheless, this tool has its uses. ** Still, this tool has its uses. ** This tool still has its uses. ** This tool has its uses, though. * The use of the word but preceded by a comma is also considered incorrect by classical grammarians. ** I was very tired, but I decided to continue. ** It was a lovely day, but rain looked likely.
