Laira – previously recorded as
Lare(1591),
Lary poynte (1638), the
Leerie (1643), and the
Lairy (1802) – was originally the name given to that part of the estuary of the
River Plym from the
Cattewater up to Marsh Mills in
Plymouth, Devon, England. The name may derive from a
Brythonic word corresponding to the
Welsh llaeru, meaning 'to ebb'.
