Student or Learner
Are the commas in this sentence used correctly? Please give an explanation why or why not. Thank you for your help.
"*My son, Mark, and I are well."
not a teacher
My son and I are well. (no comma required)
With the son's name added, two commas are required to make the sentence clear - the first, when you want to state a name after a common noun, and the second, to have a clear separation from 'and I'.
