English syntax distinguishes between phrasal verbs and adverbial adjuncts. There are differences of opinion whether these adjuncts teach better or worse than regular professors. Historically, these spice adjuncts were known as gruit. Modal options can be realized by word order (moods), modal auxiliaries and modal adjuncts. Colleges are saving money by replacing full-time professors with adjuncts. They can function as arguments, as adjuncts, or as predicative expressions. One can hence acknowledge a three-way distinction between predicative expressions, arguments, and adjuncts. There is hence a three-way distinction between predicative expressions, arguments, and adjuncts. Predicates take arguments and they permit (certain) adjuncts. Dependents here may include complements, adjuncts, and specifiers. Various conventions are used to distinguish between arguments and adjuncts in these trees. The relative clauses are adjuncts, however, not arguments. Language syntax treats adpositional phrases as units that act as arguments or adjuncts. Complement adverbials are also seen to display similar attributes as adjuncts. The distinction between arguments and adjuncts is crucial to most theories of syntax and grammar.
