Prepositions are a class of words that indicate relationships between nouns, pronouns and other words in a sentence. Most often they come before a noun.
The good news is that they never change their form, regardless of the case, gender etc. of the word they are referring to.
Prepositions are classified as simple or compound.
Simple prepositions are single word prepositions - across, after, at, before, between, by, during, from, in, into, of, on, to, under, with and without are all single word prepositions.
For example:-
- The book is on the table.
Compound prepositions are more than one word - in between and because of - are prepositions made up of two words - in front of, on behalf of - are prepositions made up of three words.
For example:-
- The book is in between War and Peace and The Lord of the Rings.
- The book is in front of the clock.
