Q. In a policy, I have to indicate that the word facility could be plural. The person editing the document has written it as facility(s). What is the correct way to portray nouns that end in y when necessary to indicate they could be singular or plural?

A. “Facility or facilities” and “one or more facilities” are both clear. And often the simple singular does just fine in implying one or more: “In the event that your facility is struck by terrorists, this contract is void.” You can see that if two facilities were struck by terrorists, the clause would apply to both.
