1. Grammar Theory
What is a Preposition?
A preposition is a word that shows the relationship between a noun or pronoun and another word in the sentence. It often connects words to show relationships of time (when), place (where), or direction (movement).
Examples: The dog jumped onto the couch. We went inside when itrained.
Common prepositions include: about, above, across, after, at, behind, by, during, for, from, in, near, of, on, over, to, with.

The Prepositional Phrase
A preposition never stands alone; it is always part of a prepositional phrase. A phrase consists of the preposition, its object (the noun or pronoun that follows it),and any modifiers in between.
Example: The squirrel ran into the alley. (into = preposition, the alley = object)
If a word like “down” or “inside” has no object, it is acting as an adverb, not a preposition.

2. Advanced Concepts
Phrasal Prepositions: Some prepositions are made of more than one word, such as because of, in spite of, according to, and instead of.
Preposition vs. Infinitive: Do not confuse the preposition to with the infinitive marker to. A preposition is followed by a noun/pronoun (I walked to school). An infinitiveis followed by a verb (I like to sleep).
