What Londyn means
Londyn has no settled meaning, because London does not. Proposals for Londinium include a personal name, a word for a wild or bold place, and a river name, and Celtic scholarship has not resolved between them.
Where Londyn comes from
Londyn respells London, recorded by the Romans as Londinium and certainly older than their arrival. Its derivation is genuinely unresolved: proposals include a Celtic personal name Londinos, read as the bold one; a pre-Celtic river name; and a compound describing a place too wet to build on, which fits the Thames floodplain. The fortified hill reading repeated on name sites is not supported by the leading place-name scholarship. As a given name Londyn is an American respelling of London and appears in our records from 1989, following the wider habit of turning a place into a girl's name with a Y.
