## Toponym

In Euskera, the town is officially called Loiu. In Spanish, the town is called Lujua.

The old name of the town was Luxua, but it was converted into Spanish after the phonetic evolution of x/j (around 17th century) in Lujua (paralleling the change Xerez -> Jerez).

In Euskera, the phonetic evolution of the toponym was different: when the -a ending was lost, phoneme x evolved in a different way to the Spanish language y, and the variation of the tonic syllable lu for lo. That is Luxu(a) -> Lu(x)u -> L(u)iu -> Loiu. Euskaltzaindia adopted Loiu as the official form of the name.. Loiu adopted its official name in 1983.
