I noticed this usage on a website of parenthethesis around a subordinate part of the sentence: is this accurate use. Rather than talk about his chocolates (which are great by the way, if you’re in Leicester you have to go!).
Sarah, noticing that the weather was changing, went back for her coat.
So the above sentence has a subordinate clause in the middle started with ''noticing'', but what is difference between splitting that with parenthesis or m-dash. Are there rules surrounding how you separate a subordinate clause
The man who is coaching my team is my father.
The man, who is coaching my team, is my father.
Is the comma use around the subordinate clause optional or are there instances where it's mandatory.
