AT vs. IN (PREPOSITIONS OF LOCATION)

Good morning. Welcome back to the Daily Vitamin.

This week's Daily Vitamins are about the difference between the prepositions AT and IN. These prepositions are easy to confuse because they are both prepositions of location (to say where something is) and prepositions of time (to say when something happens). In addition, we can find AT and IN in different expressions and in combination with other verbs and adjectives.

Today we will look at AT and IN as prepositions of location.
IN expresses the idea that an object is surrounded by or inside something else.
AT is usually used to talk about the activities that take place somewhere.

AT: We use this preposition to say where something or somebody is. We also use it to refer to a particular place:
⇒ with complete addresses
⇒ in the phrases at work and at home
⇒ to refer to shops and businesses in phrases like "at the doctor's" or, "at the butcher's"
⇒ to talk about an activity somewhere: "at a party", "at a meeting", "at lunch", "at dinner", etc. 

Examples:
⇒ I live at 927 Hamilton Road.
⇒ John is at work. He won't get home until 6 p.m.
⇒ I'm afraid I left my books at home.

IN: We use this preposition to say where something is:
⇒ inside a room--container--building--vehicle
⇒ within a geographical area (a city, a country etc.)
⇒ within an object--space--substance
⇒ held or enclosed by something (in your hands--arms etc.)

Examples:
⇒ Your books are in the bedroom.
⇒ Your clothes are in the wardrobe.
⇒ Waiter, there's a fly in my soup.

Tomorrow we will look at the difference between AT and IN for expressions of time.
