Americanisms

A fellow blogger comments on a regular basis on the lack of grammar which is prevalent in the media.
A peeve of mine is the Americanism which is slowly creeping into our language.

Here are some examples:

Americanism                                    Correct English
Prom                                                End of Year Party
Schedule (ske’dule)                         Schedule (sche’dule)
C.S.I (Crime Scene Investigator)    S.O.C.O (Scenes Of Crime Officer)
Period                                              Full Stop
Mall                                                 Shopping Precinct
Elevator                                           Lift

These words are perfectly acceptable across the Pond and there they should stay
