  London is an ancient name, attested in the first century AD, usually in the Latinised form Londinium. Modern scientific analyses of the name must account for the origins of the different forms found in early sources: Latin (usually Londinium), Old English (usually Lunden), and Welsh (usually Llundein), with reference to the known developments over time of sounds in those different languages. It is agreed that the name came into these languages from Common Brythonic; recent work tends to reconstruct the lost Celtic form of the name as * Londonjon or something similar. This was then adapted into Latin as Londinium and borrowed into Old English.
  
  Until 1889, the name "London" applied officially only to the City of London, but since then it has also referred to the County of London and to Greater London.
