I stole a cookie about ten minutes ago

I stole a cookie without regret.

What is so different about these sentences that the first adverb phrase prevents flow and requires a comma, whereas the others flow nicely and have no commas?

They follow the same order: S, V, DO, ADV…

Sentence one is not S V SO ADV. ”...about ten dollars’ worth” is a nouse phrase.

Sentence one is not S V SO ADV. ”...about ten dollars’ worth” is a nouse phrase.

Preposition functioning as a noun…So this sentence has two direct objects? I thought on the other post that you said only one was…?

About is an adverb in this sentence. And I think that about ten dollars’ worth helps define a fair bit. It’s closer to an appositive.

I have eaten a fair bit, about ten dollars worth

Yea, I also feel it is in apposition.

Can you tell me each part of speech for the phrase please? That is, about is an adverb, ten is..

Thanks a load
