I have a question about articles. I came across this sentence below:
Although Jesus himself may be perceived as heir to the legacy of Amos and Jeremiah, the Gospels present him as more than a prophet.
The author did not use an article before the word “heir”. I would add either an article of "an" or "the" before heir. People sometimes skip the article when they speak. For example: somebody called up the doctor of his father and asked:
I am son of John, how is he doing?
In the above example, I think we can skip an article before the word “son”, as it doesn't matter if John has one or more sons in this context.
But in writing, as in the example above regarding heir, I believe an article is necessary. What do you think?
(This question was inspired by Can we skip using articles in some sentences?).
