Thanks for all the questions. And even more, the explanations.
I am not sure if this is the right place, but I had a doubt about a basic thing.
Hope you can help.
Which of these is correct:
1. I, as well as John, are short.
2. I, as well as John, am short.
I feel 1. but the books say that when "other phrases are used to separate the subject from the verb, these phrases do not affect the verb." So then, logically, "as well as John" should not alter the regular verb "am".
