What are the attributive clauses and adverbial clauses guided by where?

There are two main ways to judge where to lead the positional adverbial clause or attributive clause:

When 1, where is used as the attributive clause of relative adverbs, the antecedent should be used as a component in the clause, but the positional adverbial clause guided by where is unnecessary.

2. If it is an attributive clause, there must be a modified locative noun before where; If there is no modifier noun in front of where, it is regarded as an adverbial clause of place.

Second, when where leads adverbial clauses, where is a subordinate conjunction, and the clause led by where modifies the predicate verb of the main sentence.

There is no antecedent before where to indicate a place.

Example: Make a mark where you have any body double or questions.

Mark the places where you have questions.

Usage of words:

As an adverb, Where basically means "where, where" and can be used as an interrogative adverb to guide special interrogative sentences.

Where can also be used as a relative adverb, meaning "where?" Leading restrictive and non-restrictive attributive clauses, used after words indicating places.

As a subordinate conjunction, Where can guide the adverbial clause of location, which is equivalent to in [at, to] the place. It is often preceded by emphasized words, such as just, only, even, right and so on. Or the negative word not, sometimes some components can be omitted.

Where can also guide comparative adverbial clauses, which are equivalent to while and can be translated as "while, but, and vice versa".

Where can also guide adverbial clauses with a light tone, and inversion is often used in clauses.

Where can also guide predicative clauses, and the antecedents before them are often omitted.

Where can also be followed by an infinitive phrase.
