Suppose that we have a piece of writing which is ambiguous in some parts. Now, I want to give my reason about the issue.
I want to use the noun source. (I know I can say that in many ways)
I would say:
I guess the lack of detailed context is the source of the ambiguity.
Should I use the definite article before source? I am saying that because I am not talk about a specific source.So, if I omit the article, then how different will the sentence be?
Would it be grammatical? If so, what will change?
