Shown below are prominent such light verbs, with their independent meaning first outlined, followed by their semantic contribution as auxiliaries.

This is because non-occurrences cannot be described to have occurred in a particular manner.
This passage explains how light verbs function in sentences and their limitations when describing non-occurrences.
