preposition is a word that shows the relationship between two words in the same sentence. In this case, the preposition 'of' shows a relationship between a possession or origin and other nouns or phrases. For example, 'the book of poetry' and 'the store on of the corner'.
When used as a preposition, 'of' can be used to indicate possession or origin. It is typically used to indicate origin when introducing or referencing a noun in a phrase.
1. He is a student of the university.
2. The store is of the corner.
3. She is the mother of three children.
When using 'of' to indicate possession, it is important to use the correct possessive pronoun. For example, 'the book of her' is incorrect and should be changed to 'her book'. Additionally, when indicating something as the origin of a person or thing, it is important to remember to include the article 'the' before the origin (e.g. 'the origin of the story'). Lastly, the word 'of' can often be confused with 'have', so it is important to be aware of the differences in usage.
