Here's a breakdown:
* Preposition: A word that shows the relationship between a noun or pronoun and another word in the sentence. Examples include: "on," "in," "at," "to," "from," "by," "with," "for," "about," "before," "after," "during," "since," "until," etc.
Examples of "prepositional" usage:
* Prepositional phrase: A group of words that starts with a preposition and ends with a noun or pronoun. Example: "in the garden"
* Prepositional object: The noun or pronoun that follows the preposition. Example: "in the garden"
* Prepositional complement: A prepositional phrase that functions as an adjective or adverb. Example: "The book on the table is mine." (Adjective) "She arrived before lunch." (Adverb)
So, "prepositional" generally describes anything that involves a preposition in its structure or function.
