Preposition Basics

A preposition is a word or group of words used before a noun, pronoun, or noun phrase to show direction, time, place, location, spatial relationships, or to introduce an object. Some examples of prepositions are words like "in," "at," "on," "of," and "to."
Prepositions in English are highly idiomatic. Although there are some rules for usage, much preposition usage is dictated by fixed expressions. In these cases, it is best to memorize the phrase instead of the individual preposition.

A Few Rules

Prepositions of Direction

To refer to a direction, use the prepositions "to," "in," "into," "on," and "onto."

• 
  Don’t ring the doorbell. Come right in(to) the house.
  
• 
  Drive on(to) the grass and park the car there.
  

Prepositions of Time

To refer to one point in time, use the prepositions "in," "at," and "on."
Use "in" with parts of the day (not specific times), months, years, and seasons.

Describing a film
We love watching films (= movies in American English) – either on TV, on DVD, downloaded onto our PCs or at the cinema. What sort of films do you enjoy? You've got a lot of genres to choose from: westerns (set in the American Wild West) or spaghetti westerns (those filmed in Italy) to action films (fights, car chases etc), adventure, animated (cartoons), or horror (lots of blood or ghostly visits). Perhaps you prefer comedy (or "romcom" – romantic comedy) or dramas. Sometimes these are epics (long, historical dramas) and sometimes these are adaptations (adapted either from a previous film or from a book or play). What about thrillers (or suspense), or musicals (with song and dance) and science fiction (set in a futuristic world)? Or maybe you prefer the old black and white films, or the classics
