For you writers, particularly those who use some sort of grammatical check on your efforts, I have a question.
Do you find that the program, whatever it is (I use Grammarly, obviously), insists that you insert "of" when writing things such as "a couple questions?" (I wish I could show you the red underline Grammarly put under "couple.")
I've been thinking about that, and it makes no sense to me. If I replace "couple" with "two," Grammarly objects not at all to "two questions." Nor does it object to "a few questions." That is, it does not insist on "two of questions" or "a few of questions." It seems to me that this is due to some holdover of ancient origin, and I think it's long past time that we abandon it along the roadside with the many other English aspects we've jettisoned as English has evolved. And I'm a reactionary purist when it comes to English!
