He was an exceptional planner, an amazing teacher and friend
Well, I have little doubts about the articles in this sentence.It has articles before two of the nouns and the third is left out. Doesn't seem right.
He was an exceptional planner, an amazing teacher and a friend
or
He was an exceptional planner,amazing teacher and friend.
When we say The manager and the CEO we mean two people and to mean one person we write The manager and CEO.
In this case, we're meaning one person so should not it be just one article, just one a or an ? What would be the correct sentence?
