I want to know which parts of speech words in English can serve as predicates, predicative complements, attributives, and object complements

Predicates are actually subject complements. They have the same nature as object complements and can be discussed together. As such complements, there are nouns and gerunds that express attributes, adjectives and present participles that express characteristics, and past participles that express state. In addition, infinitives, prepositional phrases, and adverbs of the same shape as prepositions can also serve as predicates and objects. complement.

Attributives are generally acted by adjectives and participles that express characteristics or states. In addition, nouns and gerunds can serve as prepositional attributives, and infinitives and prepositional phrases can serve as postpositional attributives.

The predicative complement is a grammatical component used after "be + adjective", which can be acted by of phrase, infinitive or clause.
