English Grammar Practice Test: Preposition — Flashcards

Preposition topics are: Prepositions, compound prepositions, phrase prepositions, participial prepositions, adverbs that also function as pronouns, relations expressed by pronouns, and special prepositions.

A preposition is a word or group of words that links nouns, pronouns, and phrases to other words in a sentence. They are often used to show location, which can be literal or metaphorical. 

Here are some examples of prepositions:
In: Used for locations where boundaries are present, such as walls. For example, "I was in Starbucks when I bought a coffee".
Of: Used to show a relationship or possession. For example, "The roof of the green house was orange".
For: Used to show purpose or belonging. For example, "Sara went to the store for milk". 

Here are some other examples of prepositions: At, On, To, By, With, In front of, Next to, Instead of. 

Most prepositions have multiple definitions, so their meaning depends on context. For example, "Where is your brother at?" is considered nonstandard in writing.

A preposition and its object are called a prepositional phrase. For example, "The book lies on (a preposition) the table (the object of the preposition)". 

Here are some rules for prepositions:
- Prepositions must have an object.
- Must be placed before.
- The Pronoun following the Preposition should be an object form.
- Do not confuse preposition 'to' with infinitive 'to'.
