1. Show the relationship between a noun or pronoun (the object of the preposition) and another word in the sentence. This relationship can be spatial (location), temporal (time), or directional.
* Examples:
* "The cat sat on the mat." (Spatial - location of the cat)
* "I will arrive at 8 o'clock." (Temporal - time of arrival)
* "She walked towards the store." (Directional - direction of movement)
2. Add detail and meaning to the sentence. Prepositions can make a sentence more specific and informative by providing additional context.
* Examples:
* "He went to the park." (Simple sentence)
* "He went to the park with his friends." (More detailed sentence)
Here are some additional points about prepositions:
* They typically come before a noun or pronoun, which is called the object of the preposition.
* Prepositions can be single words (e.g., on, in, at) or phrases (e.g., according to, because of).
* Some common prepositions include: on, in, at, to, from, with, by, for, about, through, during, after, before, between, among.
Overall, prepositions play a crucial role in sentence structure and meaning, helping to create clear and specific language.
