We all know what repetition is.
I'm trying to construct the following sentence:
He called out her name in an earnest, helpless repetition.
or should it be
He called out her name in earnest, helpless repetitions.
or even
He called out her name in earnest, helpless repetition.
This "repetition" I have in mind is multiple in count.
Of course, I can rewrite this using an adverb.
He called out her name repeatedly.
But my goal here is to describe the way he called out her name: earnestly, helplessly, repeatedly.
I have a sense that "repetition" can mean the act of repeating, so in this case, it's not countable. But isn't repetition also countable too?
Thank you for shedding light on this confusing situation.
