The main point of the keyword term "patriots day boston 2013" is the component "Patriots' Day," which functions grammatically as a proper noun. A proper noun is a name used for an individual person, place, or organization, and in this case, it specifically names a holiday.
The full term operates as a noun phrase where "Patriots' Day" is the head noun. The subsequent elements, "Boston" and "2013," are post-nominal modifiers that specify the particular instance of the holiday. "Boston" is a proper noun functioning as a locative adjunct, indicating place. "2013" is a numeral functioning as a temporal adjunct, indicating time. Together, these modifiers narrow the scope of the head noun to a single, identifiable event.
Identifying the main point as a proper noun is crucial because it establishes the subject of the article as a specific, singular event. This dictates that the content should be descriptive and factual, centered on the circumstances and significance of that particular holiday in that specific location and year, rather than treating the subject as a general concept or an action.
