The keyword term functions as a complex noun phrase. The grammatical head, and therefore the main point of the phrase, is the plural noun "events." The other components serve as modifiers that specify the context of these occurrences. This identification establishes that the core subject is a set of activities or happenings, not the holiday or location itself.
A grammatical analysis reveals a structure of [Modifier] + [Head Noun] + [Modifier]. The head noun is "events." It is pre-modified by "Patriots Day," a proper noun acting as a noun adjunct, which specifies the type or occasion of the events. The phrase is post-modified by "Lexington, MA," a proper noun phrase functioning as a locational adjunct, which specifies the geographical setting. This construction progressively narrows the focus from general occurrences to a highly specific set defined by time and place.
Recognizing "events" as the primary subject is crucial for article development. It dictates that the content's focus must be on describing specific activities, such as battle reenactments, parades, ceremonies, and public gatherings. The modifiers "Patriots Day" and "Lexington, MA" provide the necessary framework, but the article's core purpose should be to inform about the actual schedule and nature of these happenings, rather than to provide a general history of the holiday or a profile of the town.
