A Little Etymology

At one time (during the Victorian Era) London was the greatest city in the world.  The name London comes from the town’s ancient name,  ‘Londinium.’  Oddly, no one really knows what it means or where it came from originally.  According to the Museum of London, Londinium is not Latin but of pre-Roman origin.  Wikipedia suggests it was named by King Lud of Welsh mythology, after himself.  Wapedia suggests a common theory that it descends from the word ‘lond’, meaning ‘wild’, of Celtic origin.  Richard Coates, while professor of linguistics at  the University of Sussex, introduced an explanation that London is derived from the  pre-Celtic word (p)lowonida, meaing ‘river too wide to ford,’ referring to the Thames at London.
