Comma between an article and its noun
Commas are used to separate thoughts or ideas, or to tell the reader when to pause. Articles are used to refer to a noun, so the article can’t really be a separated from the noun as it’s all part of the same idea. The articles in English are the, a and an. Nouns are a person, place or thing.
The company managers accidentally scheduled the, weekly meeting for Saturday.
The comma between the and weekly should be removed because it separates the article the from the noun meeting.
A, bouquet of flowers may be created using more than one type of flower.
I’ll have an, apple.
When speaking, we will often pause while we think of the next word. While a speaker may pause after an article, it is not a grammatically correct pause; when written down, there should be no comma after an. Generally, this example will not come up in formal writing but if it should, the pause can be indicated with an ellipsis: I’ll have an… apple.
