Usage Note: When a noun phrase contains more than one and a singular noun, the verb is normally singular: More than one editor is working on that project. More than one field has been planted with oats. When more than one is followed by of and a plural noun, the verb is plural: More than one of the paintings were stolen. More than one of the cottages are for sale. When more than one stands alone, it usually takes a singular verb, but it may take a plural verb if the notion of multiplicity predominates: The operating rooms are all in good order. More than one is (or are) equipped with the latest imaging technology. See Usage Notes at one, over.
