I'd like to check this vocabulary:
-a box near your house: letterbox (BrE), mailbox (AmE); We don't generally have these on houses in the UK. We just have a letterbox (slot) in our front doors. However, a building containing several flats might have lots of small letterboxes attached to the outside wall. That's not always the case. I live in a building which is divided into four flats. We have just one letterbox in the front door. All the post for all four flats comes through it, lands on the floor and whichever resident gets to it first sorts through it, takes their own and puts the rest on a small table in the communal hallway.
-a public box in the street: letterbox or postbox (BrE), mailbox (AmE); :tick:
-a small opening in a door for delivering letters: letterbox (BrE), :tick: letter hole, mail slot (AmE). I don't know about the AmE versions for this one.
Can we write both 'a letter box' and 'a letterbox'?
For me, a "letter box" would be a metal box on the wall and a "letterbox" is the slot in a door.
Thanks.
