The noun group (NG) or nominal group is a grammatical construction whose core or head is a noun. The NG can consist of just the head noun or the head noun can be preceded or followed by other words that modify it. Premodifiers come before the head noun and can include articles, adjectives, possessives, demonstratives, numbers and other nouns. Postmodifiers come after the head noun and can include prepositional phrases, participial phrases, infinitive phrases and relative clauses. The NG can function as the subject, object, complement or object of a preposition in a sentence.
