Bill:

With all respect, you are mixing apples and bananas. Opera as a plural of opus is not the same word as opera as a form of theatrical performance in which a dramatic performance is set to music.

The first opera is the plural of opus, the Latin word for work. The second is from the Italian, according to my dictionary, though it does itself derive from opus. In the second form opera is singular. The plural is operas.

Now, let's get some walnuts and mayo and we can have a Waldorf salad.
