Anyone who has had the misfortune to have to beta for me will know I don't understand commas. I am trying. However there seem to be two ways of explaining them- one whereby commas define separate clauses e.g in the sentence (this will make no sense) "Abraxas Malfoy turned from the window, and by chance, saw the pot plant exploding" the "and by chance" is a separate clause and therefore is separated from the rest by commas.
Which makes sense. Most of the time. But sometimes- like this is from the back of a book I'm rereading:
"It deserves many prizes and, better than that, the affection of generations of readers"
Now, I'm pretty sure if I sent this sentence to my betas, they'd put the comma before the 'and'. However surely the commas just separate the part which is unnecessary to the sentence. i.e without the "better than that" the sentence still makes sense so the comma should go before the 'and'.
Does that make any sense at all? Any help/ answers would be greatly appreciated
