Usage Note: The preposition about is traditionally used to refer to the relation between a narrative and its subject: a book about Cézanne; a movie about the Boston Massacre. For some time, this usage has been extended beyond narratives to refer to the relation between various kinds of nouns and the things they entail or make manifest: The party was mostly about showing off their new offices. You don't understand what the women's movement is about. This controversial usage probably originates with the familiar expression all about, as in Let me tell you all about her. In our 2001 survey, 62 percent of the Usage Panel rejected about in the party example listed above, and 51 percent rejected Their business is about matching people with the right technology. In 1988, 59 percent rejected a similar example. It is probably best to limit this use of about to more informal contexts. · When followed by an infinitive, about to means "on the verge of," as in I'm about to go downtown. The construction not about to usually expresses intention or determination, as in We are not about to negotiate with terrorists. This usage was considered unacceptable in formal writing to a majority of the Usage Panel in 1988, but resistance has eroded with familiarity. Fully 82 percent accepted it in our 2001 survey.
