    Usage notes
    The modern adjectival senses of worth'' compare two noun phrases, prompting some sources to classify the word as a preposition. Most, however, list it an adjective, some with notes like "governing a noun with prepositional force." says, "the adjective ''worth requires what is most easily described as an object." Joan Maling (1983) shows that worth is best analysed as a preposition rather than an adjective. CGEL (2002) analyzes it as an adjective.
