Please, explain me should we refer to the subject as singular or plural, when there are multiple subjects in one sentence joined by the conjunction "and". I have the sentence as an example. Can we consider the subjects an individual or refer to unite element? It has confused me:

Problem resolution and elimination of root cause help to lower the number of incidents.

  • Yes. Use the plural. Commented Apr 2, 2019 at 14:01
  • It's often just a stylistic choice. In your example, plural is probably more likely, but singular is perfectly acceptable. FWIW, Americans seem to be far more wedded to "strict logic" than Brits in this respect... Commented Apr 2, 2019 at 14:19
  • AmE favours plural over singular by 2:1 with, say, early diagnosis and treatment are (essential),. But BrE apparently uses both forms about equally often. Personally, I'm a Brit, and I actually prefer singular with that one. Commented Apr 2, 2019 at 14:19

AND is a conjunction.

It is "used as a function word to indicate connection or addition especially of items within the same class" (https://www.merriam-webster.com/dictionary/and).

So we should use the plural verb form after the phrase with the conjunction as in the phrase there are two items at least.
