The keyword term is a noun phrase. The main part of speech that serves as the core subject is the noun "events". The preceding components, "september 11th" and "london," function as adjectival modifiers that specify the temporal and geographic context of these events.
In this grammatical construction, "events" is the head noun, establishing the primary subject matter. The proper noun "london" acts as a locative modifier, specifying the location. The date "september 11th" serves as a temporal modifier, specifying the time. Both "london" and "september 11th" are functioning attributively, meaning they act like adjectives to provide more specific information about the head noun. The entire phrase therefore refers to a particular set of occurrences defined by a specific time and place.
This grammatical determination is crucial because it directs the article's focus. The central theme must be the actual happenings or activities themselves. The content should be structured to describe, list, or analyze these specific occurrences. The modifiers merely define the scope, ensuring the article is not about the date or the city in general, but about the concrete events at their intersection. Therefore, the main point of the article is an exposition of these defined events.
