Can this be singular or plural depending on context? I have known it as only a sigular person.
kk131)The executive is going to come to the bargaining table this morning for talks with the labor union.
In that context, "the executive" is seen as a single body of people and takes the singular. If you referred to them individually, they would be "the executives" (referring to the people) and would take the plural.
I would say that you're more likely to see "The executive committee is going to come ..."
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
