List of words having different meanings in American and British English (A–L)

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by GangofOne (talk | contribs) at 07:25, 18 September 2005 (N). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

An incomplete list of words having differing meanings in standard British and American English.

  • Many of the definitions are recognised by the other as Britishisms or Americanisms respectively.
  • Certain words are limited to regional or specific dialect use in either usage. They will, however, be recognised and understood by most native English speakers in the country concerned. These are marked with their usual area of use.
  • Many American phrases and meanings are now used and/or understood in the UK, thanks to the ubiquity of US-made movies and television programmes.

When adding words or meanings to this list, please follow the notations used in existing entries as much as possible, e.g. those of equivalent UK/US terms and common UK/US meanings.
