Key Concepts

Structure

The basic structure is: Preposition + (Modifiers) + Object of the Preposition.

Preposition: Words like ‘in’, ‘on’, ‘at’, ‘to’, ‘from’, ‘with’, ‘by’, ‘about’, ‘over’, ‘under’.
Object of the Preposition: A noun or pronoun that the preposition relates to other words in the sentence.

Function

Prepositional phrases can act as:

Adjectives: Modifying nouns or pronouns (e.g., “The book on the table is mine.”).
Adverbs: Modifying verbs, adjectives, or other adverbs, indicating time, place, manner, etc. (e.g., “She ran with great speed.”).

Compound Prepositions: Compound words (e.g., ‘inside’, ‘outside’, ‘about’, ‘above’).
Phrasal Prepositions: Multi-word phrases acting as a single preposition (e.g., ‘according to’, ‘because of’, ‘in front of’).

Adding specific details about time, place, direction, and relationship.
