This is part of my essay that I'm writing, and I'm unsure of whether to use "has" or "have."
"that experience, and others like it, have/has taught me"
That experience has taught me, but others like it have taught me. Which one should be used in this situation?
"That experience, and others like it, have taught me" is correct, because the subject (that experience, and others like it) is plural.
The correct term is have, but you can avoid confusion altogether by leaving it out:
"that experience, and others like it, taught me"
