grammatical number - "occur" vs "occurs" with a singular collective noun
I wrote: The ability to guarantee that a batch of writes occurs together. One reviewer wanted to change that to occur . I'm not sure if this is my idiom (Australian of U.K. origin) vs American or if I'm wrong. I regarded batch of writes as a singular collective noun. This English Club reference and others suggest using a plural verb with collective noun is less common in American English. edit To clarify, the sentence is in a book about programming computer databases and the full sentence is much longer, possibly too long! Those three operations are all we need; everything else is sugar on top (or maybe something a bit more nutritious, like the ability to guarantee that a batch of writes occurs together). Answer You are correct. It should be occurs because you are talking about a batch. Now, a batch of what? That is something else.
