Usage Note: A traditional grammatical rule asserts that sentences beginning with and or but express "incomplete thoughts" and are therefore incorrect. But this stricture has been ignored by writers from Shakespeare to Joyce Carol Oates, and most of the Usage Panel sees wisdom in this attitude. In our 1988 survey, when asked whether they paid attention to the rule in their own writing, 24 percent answered "always or usually," 36 percent answered "sometimes," and 40 percent answered "rarely or never." See Usage Notes at both, but, with.


A logical operator that returns a true value only if both operands are true.
