Subordinadas sustantivas de TÉRMINO dentro del sintagma preposicional

In this video, we present a type of noun clause we haven't seen before: the TERM noun clause. This type of noun clause is the opposite of the noun clauses that are the complement of an adverb, the complement of an adjective, etc., and why? Once again, we find that grammarians are not entirely in agreement. For example, in the sentence "He left before the movie ended," what some grammarians consider "that the movie ended" is a noun clause that is the complement of an adverb (before), including the preposition "of," while other grammarians consider "that the movie ended" to be a prepositional phrase that functions as the complement of an adverb, where "of" is the link and "that the movie ended" is the noun clause that functions as the end of said prepositional phrase. We've explained the entire theory so far, following the first grammarians, who included the preposition "de" within the subordinate clause. However, based on the comments many of you have sent me, there's a tendency to favor the "term" option, and it's not entirely without good logic, as we'll explain in the video. What will JAF Academy do from now on? To avoid disappointing either party, always explain both forms.
