The noun itself, being literally singular both in form and in fact, has not unfrequently some article or adjective before it that implies unity; so that the interpretation of it in a plural sense by the pronoun or verb, was perhaps not improperly regarded by the old grammarians as an example of the figure syllepsis:.

I therefore omit some forms of expression which others have treated as examples of syllepsis, and define the term with reference to such as seem more worthy to be noticed as deviations from the ordinary construction of words.
