 This name may be derived from the Brittonic "*lāto-" meaning "rut, heat" (in animals ready to mate), an element represented in Welsh as "llawd", "heat", and possibly cognate to Greek "plōtós", "flowing".It has been surmised that the name denoted either a forest covering most of the kingdom of Elmet, which existed during the fifth century into the early seventh, or an early river-name, presumably that of the River Aire.An inhabitant of Leeds is locally known as a "Loiner", possibly derived from Loidis.
